     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an optical image capturing system, and more particularly to a compact optical image capturing system which can be applied to electronic products. 
     2. Description of the Related Art 
     In recent years, with the rise of portable electronic devices having camera functionalities, the demand for an optical image capturing system has gradually been raised. The image sensing device of the ordinary photographing camera is commonly selected from a charge coupled device (CCD) or a complementary metal-oxide semiconductor sensor (CMOS Sensor). Also, as advanced semiconductor manufacturing technology enables the minimization of the pixel size of the image sensing device, the development of the optical image capturing system has gravitated towards the field of high pixels. Therefore, the requirement for high image quality has been rapidly increasing. 
     The traditional optical image capturing system of a portable electronic device comes with different designs, including a four-lens or a five-lens design. However, the requirement for the higher pixels and the requirement for a large aperture of an end user, like functionalities of micro filming and night view, or the requirement of wide angle of view of the portable electronic device have been raised, thus the optical image capturing system in prior arts cannot meet the requirement of the higher order camera lens module. 
     Therefore, how to effectively increase quantity of incoming light of the optical image capturing system, and further improve image quality for the image formation, has become an important issue. 
     SUMMARY OF THE INVENTION 
     The aspect of embodiment of the present invention directs to an optical image capturing system which use combination of refractive power, convex and concave surfaces of six-piece optical lenses (the convex or concave surface in the present invention denotes the change of geometrical shape of an object side or an image side of each lens with different height from an optical axis) to increase the quantity of incoming light of the optical image capturing system, and to improve image quality for image formation, so as to be applied to compact electronic products.

     The inflection points on the object sides or the image side of the other lenses and the distances perpendicular to the optical axis thereof or the sinkage values thereof are denoted in a similar way described above. 
     The Lens Parameters Related to the Aberration 
     Optical distortion for image formation in the optical image capturing system is denoted by ODT. TV distortion for image formation in the optical image capturing system is denoted by TDT. Further, the degree of aberration offset within a range of 50% to 100% of the field of view of the image can be further limited. An offset of the spherical aberration is denoted by DFS. An offset of the coma aberration is denoted by DFC. 
     The characteristic diagram of modulation transfer function of the optical image capturing system is used for testing and evaluating the contrast ratio and the sharpness ratio of the image. The vertical coordinate axis of the characteristic diagram of modulation transfer function indicates a contrast transfer rate (with values from 0 to 1). The horizontal coordinate axis indicates a spatial frequency (cycles/mm; lp/mm; line pairs per mm). Theoretically, an ideal image capturing system can clearly and distinctly show the line contrast of a photographed object. However, the values of the contrast transfer rate at the vertical coordinate axis are smaller than 1 in the actual optical image capturing system. In addition, to achieve a fine degree of recovery in the edge region of the image is generally more difficult than in the central region of the image. The contrast transfer rates (MTF values) with spatial frequencies of 55 cycles/mm at the optical axis, 0.3 field of view and 0.7 field of view of visible light spectrum on the image plane may be expressed respectively as MTFE0, MTFE3 and MTFE7. The contrast transfer rates (MTF values) with spatial frequencies of 110 cycles/mm at the optical axis, 0.3 field of view, and 0.7 field of view of visible light spectrum on the image plane may be respectively expressed as MTFQ0, MTFQ3 and MTFQ7. The contrast transfer rates (MTF values) with spatial frequencies of 220 cycles/mm at the optical axis, 0.3 field of view, and 0.7 field of view of visible light spectrum on the image plane may be respectively expressed as MTFH0, MTFH3 and MTFH7. The contrast transfer rates (MTF values) with spatial frequencies of 440 cycles/mm at the optical axis, 0.3 field of view, and 0.7 field of view of visible light spectrum on the image plane may be respectively expressed as MTF0, MTF3 and MTF7. The three fields of view described above are representative to the center, the internal field of view and the external field of view of the lens. Therefore, the three fields of view described above may be used to evaluate whether the performance of the specific optical image capturing system is excellent. If the design of the optical image capturing system corresponds to a sensing device which pixel size is below and equal to 1.12 micrometers, the quarter spatial frequencies, the half spatial frequencies (half frequencies) and the full spatial frequencies (full frequencies) of the characteristic diagram of modulation transfer function are respectively at least 110 cycles/mm, 220 cycles/mm and 440 cycles/mm. 
     If an optical image capturing system needs to satisfy conditions with images of the visible spectrum and the infrared spectrum simultaneously, such as the requirements for night vision in low light, the used wavelength may be 850 nm or 800 nm. Since the main function is to recognize the shape of an object formed in a black-and-white environment, high resolution is unnecessary and thus the spatial frequency which is less than 110 cycles/mm may be selected to evaluate the performance of the specific optical image capturing system on the infrared light spectrum. When the operation wavelength 850 nm is focused on the image plane, the contrast transfer rates (MTF values) with a spatial frequency of 55 cycles/mm where the images are at the optical axis, 0.3 field of view and 0.7 field of view may be respectively expressed as MTFI0, MTFI3 and MTFI7. However, because the difference between the infrared wavelength of 850 nm or 800 nm and the general visible light wavelength is large, the optical image capturing system which not only has to focus on the visible light and the infrared light (dual-mode) but also has to achieve a certain function in the visible light and the infrared light respectively has a significant difficulty in design. 
     The present invention provides an optical image capturing system, an object side or an image side of the sixth lens may have inflection points, such that the angle of incidence from each field of view to the sixth lens can be adjusted effectively and the optical distortion and the TV distortion can be corrected as well. Furthermore, the surfaces of the sixth lens may have a better optical path adjusting ability to acquire better image quality.

     The present invention provides an optical image capturing system, from an object side to an image side, comprising a first lens with negative refractive power, a second lens with positive refractive power, a third lens with positive refractive power, a fourth lens with negative refractive power, a fifth lens with positive refractive power, a sixth lens with negative refractive power, and an image plane.

     The arc length of any surface of a single lens within the maximum effective half diameter affects the surface&#39;s ability to correct the aberration and the optical path differences between each of the fields of view. The longer the arc length is, the better the ability to correct the aberration will be. However, difficulties may be found in the manufacturing process. Therefore, it is necessary to control the arc length of any surface of a single lens within the maximum effective half diameter, especially the ratio (ARS/TP) between the arc length (ARS) of the surface within the maximum effective half diameter and the thickness (TP) of the lens to which the surface belongs on the optical axis. For instance, ARS11 denotes the arc length of the maximum effective half diameter of the object side surface of the first lens. TP1 denotes the thickness of the first lens on the optical axis. The ratio between the two is ARS11/TP1. ARS12 denotes the arc length of the maximum effective half diameter of the image side surface of the first lens. The ratio between ARS12 and TP1 is ARS12/TP1. ARS21 denotes the arc length of the maximum effective half diameter of the object side surface of the second lens. TP2 denotes the thickness of the second lens on the optical axis. The ratio between the two is ARS21/TP2. ARS22 denotes the arc length of the maximum effective half diameter of the image side surface of the second lens. The ratio between ARS22 and TP2 is ARS22/TP2. The ratio between the arc length of the maximum effective half diameter of any surface of the rest lenses in the optical image capturing module and the thickness (TP) of the lens to which the surface belongs on the optical axis may be deducted on this basis. 
     The thickness of a single lens at a height of ½ entrance pupil diameter (HEP) particularly affects the corrected aberration of common area of each field of view of light and the capability of correcting the optical path difference between each field of view of light in the scope of ½ entrance pupil diameter (HEP). The capability of aberration correction is enhanced if the thickness of the lens becomes greater, but the difficulty for manufacturing is also increased at the same time. Therefore, the thickness of a single lens at the height of ½ entrance pupil diameter (HEP) needs to be controlled. The ratio relationship (ETP/TP) between the thickness (ETP) of the lens at a height of ½ entrance pupil diameter (HEP) and the thickness (TP) of the lens on the optical axis needs to be controlled in particular. For example, the thickness of the first lens at a height of ½ entrance pupil diameter (HEP) may be expressed as ETP1. The thickness of the second lens at a height of ½ entrance pupil diameter (HEP) may be expressed as ETP2. The thicknesses of other lenses at a height of ½ entrance pupil diameter (HEP) in the optical image capturing system are expressed in a similar way. The sum of ETP1 to ETP6 described above may be expressed as SETP. The embodiments of the present invention may satisfy the following condition: 0.3≤SETP/EIN&lt;1. 
     In order to achieve a balance between enhancing the capability of aberration correction and reducing the difficulty for manufacturing, the ratio relationship (ETP/TP) between the thickness (ETP) of the lens at the height of ½ entrance pupil diameter (HEP) and the thickness (TP) of the lens on the optical axis needs to be controlled in particular. For example, the thickness of the first lens at the height of ½ entrance pupil diameter (HEP) may be expressed as ETP1. The thickness of the first lens on the optical axis may be expressed as TP1. The ratio between ETP1 and TP1 may be expressed as ETP1/TP1. The thickness of the second lens at the height of ½ entrance pupil diameter (HEP) may be expressed as ETP2. The thickness of the second lens on the optical axis may be expressed as TP2. The ratio between ETP2 and TP2 may be expressed as ETP2/TP2. The ratio relationships between the thicknesses of other lenses at height of ½ entrance pupil diameter (HEP) and the thicknesses (TP) of the lens on the optical axis lens in the optical image capturing system are expressed in a similar way. The embodiments of the present invention may satisfy the following condition: 0.2≤ETP/TP≤3. 
     The horizontal distance between two adjacent lenses at height of ½ entrance pupil diameter (HEP) may be expressed as ED. The horizontal distance (ED) described above is parallel to the optical axis of the optical image capturing system and particularly affects the corrected aberration of common area of each field of view of light and the capability of correcting the optical path difference between each field of view of light at the position of ½ entrance pupil diameter (HEP). The capability of aberration correction may be enhanced if the horizontal distance becomes greater, but the difficulty for manufacturing is also increased and the degree of ‘miniaturization’ to the length of the optical image capturing system is restricted. Therefore, the horizontal distance (ED) between two specific adjacent lens at the height of ½ entrance pupil diameter (HEP) must be controlled. 
     In order to achieve a balance between enhancing the capability of correcting aberration and reducing the difficulty for ‘minimization’ to the length of the optical image capturing system, the ratio relationship (ED/IN) of the horizontal distance (ED) between the two adjacent lenses at height of ½ entrance pupil diameter (HEP) to the horizontal distance (IN) between the two adjacent lenses on the optical axis particularly needs to be controlled. For example, the horizontal distance between the first lens and the second lens at height of ½ entrance pupil diameter (HEP) may be expressed as ED12. The horizontal distance on the optical axis between the first lens and the second lens may be expressed as IN12. The ratio between ED12 and IN12 may be expressed as ED12/IN12. The horizontal distance between the second lens and the third lens at height of ½ entrance pupil diameter (HEP) may be expressed as ED23. The horizontal distance on the optical axis between the second lens and the third lens may be expressed as IN23. The ratio between ED23 and IN23 may be expressed as ED23/IN23. The ratio relationships of the horizontal distances between other two adjacent lenses in the optical image capturing system at height of ½ entrance pupil diameter (HEP) to the horizontal distances on the optical axis between the two adjacent lenses are expressed in a similar way. 
     The horizontal distance parallel to the optical axis from a coordinate point on the image side of the sixth lens at height ½ HEP to the image plane may be expressed as EBL. The horizontal distance parallel to the optical axis from an intersection point where the image side of the sixth lens crosses the optical axis to the image plane may be expressed as BL. The embodiments of the present invention are able to achieve a balance between enhancing the capability of aberration correction and reserving space to accommodate other optical lenses and the following condition may be satisfied: 0.2≤EBL/BL&lt;1.1. The optical image capturing system may further include a light filtering element. The light filtering is located between the sixth lens and the image plane. The distance parallel to the optical axis from a coordinate point on the image side of the sixth lens at height of ½ HEP to the light filtering may be expressed as EIR. The distance parallel to the optical axis from an intersection point where the image side of the sixth lens crosses the optical axis to the light filtering may be expressed as PIR. The embodiments of the present invention may satisfy the following condition: 0.1≤EIR/PIR≤1.1. 
     The height of optical system (HOS) may be reduced to achieve the minimization of the optical image capturing system when the absolute value of f1 is larger than f6 (|f1|&gt;|f6|). 
     When |f2|+|f3|+|f4|+|f5|&gt;|f1|+|f6| and the aforementioned conditions are satisfied, at least one lens among the second lens to the fifth lens may have a weak positive refractive power or a weak negative refractive power. The weak refractive power indicates that an absolute value of the focal length of a specific lens is greater than 10 mm. When at least one lens among the second lens to the fifth lens has the weak positive refractive power, the positive refractive power of the first lens can be shared by this configuration, such that the unnecessary aberration will not appear too early. On the contrary, when at least one lens among the second lens to the fifth lens has the weak negative refractive power, the aberration of the optical image capturing system can be slightly corrected. 
     Besides, the sixth lens may have negative refractive power, and the image side thereof may be a concave surface. Hereby, this configuration is beneficial to shorten the back focal length of the optical image capturing system so as to keep the optical image capturing system minimized. Moreover, at least one surface of the sixth lens may possess at least one inflection point, which is capable of effectively reducing the incident angle of the off-axis rays, thereby further correcting the off-axis aberration.

     The equation for the aspheric surface as mentioned above is: 
         z=ch   2 /[1+[1−( k+ 1) c   2   h   2 ] 0.5 ]+ A 4 h   4   +A 6 h   6   +A 8 h   8   +A 10 h   10   +A 12 h   12   +A 14 h   14   +A 16 h   16   +A 18 h   18   +A 20 h   20 + . . .   (1)
 
     wherein, z is the position value of the position along the optical axis at the height h where the surface apex is regarded as a reference; k is the conic coefficient; c is the reciprocal of curvature radius; and A4, A6, A8, A10, A12, A14, A16, A18, and A20 are high order aspheric coefficients. 
     In the optical image capturing module provided by the present disclosure, the material of the lens may be made of glass or plastic. Using plastic as the material for producing the lens may effectively reduce the cost of manufacturing. In addition, using glass as the material for producing the lens may control the heat effect and increase the designed space configured by the refractive power of the optical image capturing module. Moreover, the object side surface and the image side surface from the first lens to the sixth lens may be aspheric, which may obtain more control variables. Apart from eliminating the aberration, the number of lenses used may be reduced compared with that of traditional lenses used made by glass. Thus, the total height of the optical image capturing module may be reduced effectively. 
     Furthermore, in the optical image capturing system provided by the present invention, when the surface of the lens is a convex surface, the surface of the lens adjacent to the optical axis is convex in principle, and when the surface of the lens is a concave surface, the surface of the lens adjacent to the optical axis is concave in principle. 
     The optical image capturing system of the present invention can be applied to the optical image capturing system with automatic focus based on the demand and has the characteristics of good aberration correction and good image quality. Thereby, the optical image capturing system expands the application aspect. 
     The optical image capturing system of the present invention can further include a driving module based on the demand. The driving module may be coupled with the lens and enable the movement of the lens. The foregoing driving module may be the voice coil motor (VCM) which is applied to move the lens to focus, or may be the optical image stabilization (OIS) which is applied to reduce the frequency which lead to the out focus due to the vibration of the camera lens in the shooting process. 
     At least one of the first lens, the second lens, the third lens, the fourth lens, the fifth lens and the sixth lens of the optical image capturing system of the present invention may further be designed as a light filtering element with a wavelength of less than 500 nm based on the demand. The light filtering element may be made by coating film on at least one surface of that lens with certain filtering function, or forming that lens with material that can filter light with short wavelength. 
     The image plane of the optical image capturing system of the present invention may be a plane or a curved surface based on the design requirements. When the image plane is a curved surface (e.g. a spherical surface with curvature radius), the decrease of the required incident angle to focus rays on the image plane is helpful. In addition to the aid of the miniaturization of the length of the optical image capturing system (TTL), this configuration is helpful to elevate the relative illumination at the same time.

     Second Embodiment 
     Please refer to  FIGS. 2A to 2C .  FIG. 2A  is a schematic view of the optical image capturing system according to the second embodiment of the present invention.  FIG. 2B  is a curve diagram illustrating the spherical aberration, astigmatism and optical distortion of the optical image capturing system in order from left to right according to the second embodiment of the present invention.  FIG. 2C  is a characteristic diagram of modulation transfer of visible light spectrum for the optical image capturing system according to the second embodiment of the present invention. As shown in  FIG. 2A , an optical image capturing system  20  includes, in the order from the object side to the image side, a first lens  210 , a second lens  220 , an aperture  200 , a third lens  230 , a fourth lens  240 , a fifth lens  250 , a sixth lens  260 , an IR-cut filter  280 , an image plane  290 , and an image sensor element  292 . 
     The first lens  210  has negative refractive power and is made of plastic. The object side  212  of the first lens  210  is a concave surface and the image side  214  of the first lens  210  is a concave surface, and the object side  212  and the image side  214  are aspheric. The object side  212  has one inflection point, and the image side  214  has one inflection point. 
     The second lens  220  has positive refractive power and is made of plastic. The object side  212  of the second lens  220  is a convex surface and the image side  224  of the second lens  220  is a concave surface, and the object side  222  and the image side  224  are aspheric. The object side  222  has one inflection point. 
     The third lens  230  has positive refractive power and is made of plastic. An object side  232  of the third lens  230  is a convex surface and an image side  234  of the third lens  230  is a convex surface, and the object side  232  and the image side  234  are both aspheric. The object side  232  has one inflection point. 
     The fourth lens  240  has negative refractive power and is made of plastic. An object side  242  of the fourth lens  240  is a convex surface and an image side  244  of the fourth lens  240  is a concave surface, and the object side  242  and the image side  244  of the fourth lens  240  are both aspheric. The object side  242  has one inflection point. 
     The fifth lens  250  has positive refractive power and is made of plastic. An object side  252  of the fifth lens  250  is a concave surface and an image side  254  of the fifth lens  250  is a convex surface, and the object side  252  and the image side  254  are both aspheric. The object side  252  has one inflection point, and the image side  254  has one inflection point. 
     The sixth lens  260  has negative refractive power and is made of plastic. An object side  262  of the sixth lens  260  is a convex surface and an image side  264  of the sixth lens  260  is a concave surface, and the object side  262  and the image side  264  are both aspheric. The object side  262  has two inflection points and the image side  264  has one inflection point. Hereby, this configuration is beneficial to shorten the back focal length of the optical image capturing system so as to keep the optical image capturing system minimized. Furthermore, the incident angle of the off-axis rays can be effectively reduced, thereby further correcting the off-axis aberration. 
     The IR-cut filter  280  is made of glass, and disposed between the sixth lens  260  and the image plane  290 , and does not affect the focal length of the optical image capturing system.

     Third Embodiment 
     Please refer to  FIGS. 3A to 3C .  FIG. 3A  is a schematic view of the optical image capturing system according to the third embodiment of the present invention.  FIG. 3B  is a curve diagram illustrating the spherical aberration, astigmatism and optical distortion of the optical image capturing system in order from left to right according to the third embodiment of the present invention.  FIG. 3C  is a characteristic diagram of modulation transfer of visible light spectrum for the optical image capturing system according to the third embodiment of the present invention. As shown in  FIG. 3A , an optical image capturing system  30  includes, in the order from the object side to the image side, a first lens  310 , a second lens  320 , an aperture  300 , a third lens  330 , a fourth lens  340 , a fifth lens  350 , a sixth lens  360 , an IR-cut filter  380 , an image plane  390 , and an image sensor element  392 . 
     The first lens  310  has negative refractive power and is made of plastic. The object side  312  of the first lens  310  is a concave surface and the image side  314  of the first lens  310  is a convex surface. The object side  312  and the image side  314  are aspheric. The object side  312  has one inflection point, and the image side  314  has one inflection point. 
     The second lens  320  has positive refractive power and is made of plastic. The object side  322  of the second lens  320  is a convex surface and the image side  324  of the second lens  320  is a concave surface, and the object side  322  and the image side  324  are aspheric. The object side  322  has one inflection point. 
     The third lens  330  has positive refractive power and is made of plastic. An object side  332  of the third lens is a convex surface and an image side  334  of the third lens  330  is a convex surface, and the object side  332  and the image side  334  are both aspheric. The object side  332  has one inflection point. 
     The fourth lens  340  has negative refractive power and is made of plastic. An object side  342  of the fourth lens  340  is a convex surface and an image side  344  of the fourth lens  340  is a concave surface, and the object side  342  and the image side  344  are both aspheric. The object side  342  has one inflection point, and the image side  344  has one inflection point. 
     The fifth lens  350  has positive refractive power and is made of plastic. An object side  352  of the fifth lens  350  is a concave surface and an image side  354  of the fifth lens is a convex surface, and the object side  352  and the image side  354  are both aspheric. The object side  352  has one inflection point and the image side  354  has one inflection point. 
     The sixth lens  360  has negative refractive power and is made of plastic. An object side  362  of the sixth lens  360  is a convex surface and an image side  364  of the sixth lens  360  is a concave surface, and the object side  362  and the image side  364  are both aspheric. The object side  362  has two inflection points and the image side  364  has one inflection point. Hereby, this configuration is beneficial to shorten the back focal length of the optical image capturing system so as to keep the optical image capturing system minimized. Furthermore, the incident angle of the off-axis rays can be effectively reduced, thereby further correcting the off-axis aberration. 
     The IR-cut filter  380  is made of plastic, and disposed between the sixth lens  360  and the image plane  390 , and does not affect the focal length of the optical image capturing system.

     Fourth Embodiment 
     Please refer to  FIGS. 4A to 4C .  FIG. 4A  is a schematic view of the optical image capturing system according to the fourth embodiment of the present invention.  FIG. 4B  is a curve diagram illustrating the spherical aberration, astigmatism and optical distortion of the optical image capturing system in order from left to right according to the fourth embodiment of the present invention.  FIG. 4C  is a characteristic diagram of modulation transfer of visible light spectrum for the optical image capturing system according to the fourth embodiment of the present invention. As shown in  FIG. 4A , an optical image capturing system  40  includes, in the order from the object side to the image side, a first lens  410 , a second lens  420 , an aperture  400 , a third lens  430 , a fourth lens  440 , a fifth lens  450 , a sixth lens  460 , an IR-cut filter  480 , an image plane  490 , and an image sensor element  492 . 
     The first lens  410  has negative refractive power and is made of plastic. The object side  412  of the first lens  410  is a concave surface and the image side  414  of the first lens  410  is a concave surface, and the object side  412  and the image side  414  are aspheric. The object side  412  has one inflection point. 
     The second lens  420  has positive refractive power and is made of plastic. The object side  422  of the second lens  420  is a convex surface and the image side  424  of the second lens  420  is a concave surface, and the object side  422  and the image side  424  are aspheric. The object side  422  has one inflection point. 
     The third lens  430  has positive refractive power and is made of plastic. An object side  432  of the third lens  430  is a convex surface and an image side  434  of the third lens  430  is a convex surface, and the object side  432  and the image side  434  are both aspheric. The object side  432  has one inflection point. 
     The fourth lens  440  has negative refractive power and is made of plastic. An object side  442  of the fourth lens  440  is a convex surface and an image side  444  of the fourth lens  440  is a concave surface, and the object side  442  and the image side  444  are both aspheric. The object side  442  has one inflection point, and the image side  444  has three inflection points. 
     The fifth lens  450  has positive refractive power and is made of plastic. An object side  452  of the fifth lens  450  is a concave surface and an image side  454  of the fifth lens  450  is a convex surface, and the object side  452  and the image side  454  are both aspheric. The object side  452  has one inflection point, and the image side  454  has one inflection point. 
     The sixth lens  460  has negative refractive power and is made of plastic. An object side  462  of the sixth lens  460  is a convex surface and an image side  464  of the sixth lens  460  is a concave surface, and the object side  462  and the image side  464  are both aspheric. The object side  462  has three inflection points and the image side  464  has one inflection point. Hereby, this configuration is beneficial to shorten the back focal length of the optical image capturing system so as to keep the optical image capturing system minimized. Furthermore, the incident angle of the off-axis rays can be effectively reduced, thereby further correcting the off-axis aberration. 
     The IR-cut filter  480  is made of glass, and disposed between the sixth lens  460  and the image plane  490 , and does not affect the focal length of the optical image capturing system.

     Sixth Embodiment 
     Please refer to  FIGS. 6A to 6C .  FIG. 6A  is a schematic view of the optical image capturing system according to the sixth embodiment of the present invention.  FIG. 6B  is a curve diagram illustrating the spherical aberration, astigmatism and optical distortion of the optical image capturing system in order from left to right according to the sixth embodiment of the present invention.  FIG. 6C  is a characteristic diagram of modulation transfer of visible light spectrum for the optical image capturing system according to the sixth embodiment of the present invention. As shown in  FIG. 6A , an optical image capturing system  60  includes, in the order from the object side to the image side, a first lens  610 , a second lens  620 , an aperture  600 , a third lens  630 , a fourth lens  640 , a fifth lens  650 , a sixth lens  660 , an IR-cut filter  680 , an image plane  690 , and an image sensor element  692 . 
     The first lens  610  has negative refractive power and is made of plastic. The object side  612  of the first lens  610  is a concave surface and the image side  614  of the first lens  610  is a concave surface, and the object side  612  and the image side  614  are aspheric. The object side  612  has one inflection point, and the image side  614  has one inflection point. 
     The second lens  620  has positive refractive power and is made of plastic. The object side  622  of the second lens  620  is a convex surface and the image side  624  of the second lens  620  is a concave surface, and the object side  622  and the image side  624  are aspheric. The object side  622  has one inflection point. 
     The third lens  630  has positive refractive power and is made of plastic. An object side  632  of the third lens  630  is a convex surface and an image side  634  of the third lens  630  is a convex surface, and the object side  632  and the image side  634  are both aspheric. The object side  632  has one inflection point. 
     The fourth lens  640  has negative refractive power and is made of plastic. An object side  642  of the fourth lens  640  is a convex surface and an image side  644  of the fourth lens  640  is a concave surface, and the object side  642  and the image side  644  are both aspheric. The object side  642  has one inflection point. 
     The fifth lens  650  has positive refractive power and is made of plastic. An object side  652  of the fifth lens  650  is a concave surface and an image side  654  of the fifth lens  650  is a convex surface, and the object side  652  and the image side  654  are both aspheric. The object side  652  has one inflection point and the image side  654  has one inflection point. 
     The sixth lens  660  has negative refractive power and is made of plastic. An object side  662  of the sixth lens  660  is a convex surface and an image side  664  of the sixth lens  660  is a concave surface, and the object side  662  and the image side  664  are both aspheric. The object side  662  has two inflection points and the image side  664  has one inflection point. Hereby, this configuration is beneficial to shorten the back focal length of the optical image capturing system so as to keep the optical image capturing system minimized. Furthermore, the incident angle of the off-axis rays can be effectively reduced, thereby further correcting the off-axis aberration. 
     The IR-cut filter  680  is made of glass, and disposed between the sixth lens  660  and the image plane  690 , and does not affect the focal length of the optical image capturing system.
