The length of the outline curve of any surface of a signal lens element in the maximum effective half diameter position affects the functions of the surface aberration correction and the optical path difference in each view field. The longer outline curve may lead to a better function of aberration correction, but the difficulty of the production may become inevitable. Hence, the length of the outline curve of the maximum effective half diameter position of any surface of a signal lens element (ARS) has to be controlled, and especially, the ratio relations (ARS/TP) between the length of the outline curve of the maximum effective half diameter position of the surface (ARS) and the thickness of the lens element to which the surface belongs on the optical axis (TP) has to be controlled. For example, the length of the outline curve of the maximum effective half diameter position of the object-side surface of the first lens element is denoted as ARS11, and the thickness of the first lens element on the optical axis is TP1, and the ratio between both of them is ARS11/TP1. The length of the outline curve of the maximum effective half diameter position of the. image-side surface of the first lens element is denoted as ARS12, and the ratio between ARS12 and TPI is ARS12/TP1. The length of the outline curve of the maximum effective half diameter position of the object-side surface of the second lens element is denoted as ARS21, and the thickness of the second lens element on the optical axis is TP2, and the ratio between both of them is ARS21/TP2. The length of the outline curve of the maximum effective half diameter position of the image-side surface of the second lens element is denoted as ARS22, and the ratio between ARS22 and TP2 is ARS22/TP2. The ratio relations between the lengths of the outline curve of the maximum effective half diameter position of any surface of the other lens elements and the thicknesses of the lens elements to which the surfaces belong on the optical axis (TP) are denoted in the similar way.
The length of outline curve of half of an entrance pupil diameter of any surface of a single lens element especially affects the functions of the surface aberration correction and the optical path difference in each shared view field The longer outline curve may lead to a better function of aberration correction, but the difficulty of the production may become inevitable. Hence, the length of outline curve of half of an entrance pupil diameter of any surface of a single lens element has to be controlled, and especially, the ratio relationship between the length of outline curve of half of an entrance pupil diameter of any surface of a single lens element and the thickness on the optical axis has to be controlled. For example, the length of outline curve of the half of the entrance pupil diameter of the object-side surface of the first lens element is denoted as ARE11, and the thickness of the first lens element on the optical axis is TP1, and the ratio thereof is ARE11/TP1. The length of outline curve of the half of the entrance pupil diameter of the image-side surface of the first lens element is denoted as ARE12, and the thickness of the first lens element on the optical axis is TP1, and the ratio thereof is ARE12/TP1. The length of outline curve of the half of the entrance pupil diameter of the object-side surface of the first lens element is denoted as ARE21, and the thickness of the second lens element on the optical axis is TP2, and the ratio thereof is ARE21/TP2. The length of outline curve of the half of the entrance pupil diameter of the image-side surface of the second lens element is denoted as ARE22, and the thickness of the second lens element on the optical axis is TP2, and the ratio thereof is ARE22/TP2.

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|>f6).
When |f2|+|f3|+|f4|+|f5 | and |f1|+|f6| are satisfied with above relations, at least one of the second through fifth lens elements may have weak positive refractive power or weak negative refractive power. The weak refractive power indicates that an absolute value of the focal length of a specific lens element is greater than 10. When at least one of the second through fifth lens elements has the weak positive refractive power, the positive refractive power of the first lens element can be shared, such that the unnecessary aberration will not appear too early. On the contrary, when at least one of the second through fifth lens elements has the weak negative refractive power, the aberration of the optical image capturing system can be corrected and fine tuned.
The sixth lens element may have negative refractive power and a concave image-side surface. Hereby, the back focal length is reduced for keeping the miniaturization, to miniaturize the lens element effectively. In addition, at least one of the object-side surface and the image-side surface of the sixth lens element may have at least one inflection point, such that the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further.

The Second Embodiment (Embodiment 2)
Please refer to FIG. 2A, FIG. 2B and FIG. 2C, FIG. 2A is a schematic view of the optical image capturing system according to the second embodiment of the present application. FIG. 2B is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the second embodiment of the present application, and FIG. 2C is a lateral aberration diagram of tangential fan, sagittal fan, the longest operation wavelength and the shortest operation wavelength passing through an edge of the entrance pupil and incident on the image plane by 0.7 HOI according to the second embodiment of the present application. As shown in FIG. 2A, in order from an object side to an image side, the optical image capturing system includes a first lens element 210, a second lens element 220, a third lens element 230, an aperture stop 200, a fourth lens element 240, a fifth lens element 250, a sixth lens element 260, an IR-bandstop filter 280, an image plane 290, and an image sensing device 292.
The first lens element 210 has negative refractive power and it is made of glass material. The first lens element 210 has a convex object-side surface 212 and a concave image-side surface 214, and both of the object-side surface 212 and the image-side surface 214 are aspheric.
The second lens element 220 has negative refractive power and it is made of plastic material. The second lens element 220 has a concave object-side surface 222 and a concave image-side surface 224, and both of the object-side surface 222 and the image-side surface 224 are aspheric.
The third lens element 230 has positive refractive power and it is made of glass material. The third lens element 230 has a convex object-side surface 232 and a convex image-side surface 234, and both of the object-side surface 232 and the image-side surface 234 are aspheric.
The fourth lens element 240 has positive refractive power and it is made of plastic material. The fourth lens element 240 has a convex object-side surface 242 and a convex image-side surface 244, and both of the object-side surface 242 and the image-side surface 244 are aspheric.

The Fourth Embodiment (Embodiment 4)
Please refer to FIG. 4A, FIG. 4B and FIG. 4C, FIG. 4A is a schematic view of the optical image capturing system according to the fourth embodiment of the present application, FIG. 4B is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the fourth embodiment of the present application, and FIG. 4C is a lateral aberration diagram of tangential fan, sagittal fan, the longest operation wavelength and the shortest operation wavelength passing through an edge of the entrance pupil and incident on the image plane by 0.7 HOI according to the fourth embodiment of the present application. As shown in FIG. 4A, in order from an object side to an image side, the optical image capturing system includes a first lens element 410, a second lens element 420, a third lens element 430, an aperture stop 400, a fourth lens element 440, a fifth lens element 450, a sixth lens element 460, an IR-bandstop filter 480, an image plane 490, and an image sensing device 492.
The first lens element 410 has negative refractive power and it is made of glass material. The first lens element 410 has a convex object-side surface 412 and a concave image-side surface 414, and both of the object-side surface 412 and the image-side surface 414 are aspheric.
The second lens element 420 has negative refractive power and it is made of plastic material. The second lens element 420 has a convex object-side surface 422 and a concave image-side surface 424, and both of the object-side surface 422 and the image-side surface 424 are aspheric. The object-side surface 422 has an inflection point.
The third lens element 430 has negative refractive power and it is made of glass material. The third lens element 430 has a convex object-side surface 432 and a concave image-side surface 434, and both of the object-side surface 432 and the image-side surface 434 are aspheric.
The fourth lens element 440 has positive refractive power and it is made of plastic material. The fourth lens element 440 has a convex object-side surface 442 and a convex image-side surface 444, and both of the object-side surface 442 and the image-side surface 444 are aspheric.
The fifth lens element 450 has positive refractive power and it is made of plastic material. The fifth lens element 450 has a convex object-side surface 452 and a convex image-side surface 454, and both of the object-side surface 452 and the image-side surface 454 are aspheric. The object-side surface 452 has an inflection point.
The sixth lens element 460 has negative refractive power and it is made of plastic material. The sixth lens element 460 has a concave object-side surface 462 and a convex image-side surface 464. The object-side surface 462 has two inflection points and the image-side surface 464 has an inflection point. Hereby, the back focal length is reduced to miniaturize the lens element effectively. In addition, the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further.
The IR-bandstop filler 480 is made of plastic material without affecting the focal length of the optical image capturing system and it is disposed between the sixth lens element 460 and the image plane 490.
In the optical image capturing system of the fourth embodiment, a sum of focal lengths of all lens elements with positive refractive power is ΣPP. The following relation is satisfied: ΣPP=13.152 mm and f5/ΣPP=−0.469. Hereby, it is favorable for allocating the positive refractive power of a single lens element to other positive lens elements and the significant aberrations generated in the process of moving the incident light can be suppressed.
In the optical image capturing system of the fourth embodiment, a sum of focal lengths of all lens elements with negative refractive power is ΣNP. The following relation is satisfied: ΣNP=−89.341 mm and f1/ΣNP=0.125. Hereby, it is favorable for allocating the negative refractive power of a single lens element to other negative lens elements.
Please refer to the following Table 7 and Table 8.
The detailed data of the optical image capturing system of the fourth embodiment is as shown in Table 7.

Please refer to FIG. 5A, FIG. 5B and FIG. 5C, FIG. 5A is a schematic view of the optical image capturing system according to the fifth embodiment of the present application, FIG. 5B is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the fifth embodiment of the present application, and FIG. 5C is a lateral aberration diagram of tangential fan, sagittal fan, the longest operation wavelength and the shortest operation wavelength passing through an edge of the entrance pupil and incident on the image plane by 0.7 HOI according to the fifth embodiment of the present application. As shown in FIG. 5A, in order from an object side to an image side, the optical image capturing system includes a first lens element 510, a second lens element 520, a third lens element 530, an aperture stop 500, a fourth lens element 540, a fifth lens element 550, a sixth lens element 560, an IR-bandstop filter 580, an image plane 590, and an image sensing device 592.
The first lens element 510 has negative refractive power and it is made of glass material. The first lens element 510 has a convex object-side surface 512 and a concave image-side surface 514, and both of the object-side surface 512 and the image-side surface 514 are aspheric.
The second lens element 520 has negative refractive power and it is made of plastic material. The second lens element 520 has a convex object-side surface 522 and a concave image-side surface 524, and both of the object-side surface 522 and the image-side surface 524 are aspheric.
The third lens element 530 has positive refractive power and it is made of glass material. The third lens element 530 has a convex object-side surface 532 and a concave image-side surface 534, and both of the object-side surface 532 and the image-side surface 534 are aspheric.
The fourth lens element 540 has positive refractive power and it is made of plastic material. The fourth lens element 540 has a concave object-side surface 542 and a convex image-side surface 544, and both of the object-side surface 542 and the image-side surface 544 are aspheric.
The fifth lens element 550 has positive refractive power and it is made of plastic material. The fifth lens element 550 has a convex object-side surface 552 and a convex image-side surface 554, and both of the object-side surface 552 and the image-side surface 554 are aspheric.
The sixth lens element 560 has negative refractive power and it is made of plastic material. The sixth lens element 560 has a concave object-side surface 562 and a convex image-side surface 564 The image-side surface 564 has an inflection point. Hereby, the back focal length is reduced to miniaturize the lens element effectively. In addition, the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further.
The IR-bandstop filter 580 is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the sixth lens element 560 and the image plane 590.
In the optical image capturing system of the fifth embodiment, a sum of focal lengths of all lens elements with positive refractive power is ΣPP. The following relation is satisfied: ΣPP=29.682 mm and f5/ΣPP=−0.202. Hereby, it is favorable for allocating the positive refractive power of a single lens element to other positive lens elements and the significant aberrations generated in the process of moving the incident light can be suppressed.
In the optical image capturing system of the fifth embodiment, a sum of focal lengths of all lens elements with negative refractive power is ΣNP. The following relation is satisfied: ΣNP=−29.887 mm and f1/ΣNP=0.324. Hereby, it is favorable for allocating the negative refractive power of a single lens element to other negative lens elements.
Please refer to the following Table 9 and Table 10.
The detailed data of the optical image capturing system of the fifth embodiment is as shown in Table 9.

The Seventh Embodiment (Embodiment 7)
Please refer to FIG. 7A, FIG. 7B and FIG. 7C, FIG. 7A is a schematic view of the optical image capturing system according to the seventh Embodiment of the present application, FIG. 7B is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according. to the seventh Embodiment of the present application, and FIG. 7C is a lateral aberration diagram of tangential fan, sagittal fan, the longest operation wavelength and the shortest operation wavelength passing through an edge of the entrance pupil and incident on the image plane by 0.7 HOI according to the seventh embodiment of the present application. As shown in FIG. 7A, in order from an object side to an image side, the optical image capturing system includes a first lens element 710, a second lens element 720 an aperture stop 700, a third lens element 730, a fourth lens element 740, a fifth lens element 750, a sixth lens element 760, an IR-bandstop filter 780, an image plane 790, and an image sensing device 792.
The first lens element 710 has negative refractive power and it is made of glass material. The first lens element 710 has a convex object-side surface 712 and a concave image-side surface 714, and both of the object-side surface 712 and the image-side surface 714 are aspheric.
The second lens element 720 has positive refractive power and it is made of plastic material. The second lens element 720 has a convex object-side surface 722 and as concave image-side surface 724, and both of the object-side surface 722 and the image-side surface 724 are aspheric.
The third lens element 730 has positive refractive power and it is made of glass material. The third lens element 730 has a convex object-side surface 732 and a convex image-side surface 734 and both of the object-side surface 732 and the image-side surface 734 are aspheric.
The fourth lens element 740 has negative refractive power and it is made of plastic material. The fourth lens element 740 has a concave object-side surface 742 and a convex image-side surface 744, and both of the object-side surface 742 and the image-side surface 744 are aspheric. The image-side surface 744 has an inflection point.
The fifth lens element 750 has positive refractive power and it is made of plastic material. The fifth lens element 750 has a concave object-side surface 752 and a convex image-side surface 754, and both of the object-side surface 752 and the image-side surface 754 are aspheric. The image-side surface 754 has an inflection point.
The sixth lens element 760 has positive refractive power and it is made of plastic material. The sixth lens element 760 has a concave object-side surface 762 and a convex image-side surface 764. The convex image-side surface 764 has an inflection point. Hereby, the back focal length is reduced to miniaturize the lens element effectively. In addition, the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further.
The IR-bandstop filter 780 is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the sixth lens element 760 and the image plane 790.
In the optical image capturing system of the seventh embodiment, a sum of focal lengths of all lens elements with positive refractive power is ΣPP. The following relations are satisfied: ΣPP=48.184 mm and f5/ΣPP=0.109. Hereby, it is favorable for allocating the positive refractive power of a single lens element to other positive lens elements and the significant aberrations generated in the process of moving the incident light can be suppressed.
In the optical image capturing system of the seventh embodiment, a sum of focal lengths of all lens elements with negative refractive power is ΣNP. The following relations are satisfied: ΣNP=−7.972 mm and f1/ΣNP 0.665. Hereby, it is favorable for allocating the negative refractive power of a single lens element to other negative lens elements.
Please refer to the following Table 13 and Table 14.
The detailed data of the optical image capturing system of the seventh Embodiment is as shown in Table 13.

The Eighth Embodiment (Embodiment 8)
Please refer to FIG. 8A, FIG. 8B and FIG. 8C, FIG. 8A is a schematic view of the optical image capturing system according to the eighth Embodiment of the present application, FIG. 8B is longitudinal spherical aberration curves, astigmatic field curves, and an optical distortion curve of the optical image capturing system in the order from left to right according to the eighth Embodiment of the present application, and FIG. 8C is a lateral aberration diagram of tangential fan, sagittal fan, the longest operation wavelength and the shortest operation wavelength passing through an edge of the entrance pupil and incident on the image plane by 0.7 HOI according to the eighth embodiment of the present application. As shown in FIG. 8A, in order from an object side to an image side, the optical image capturing system includes an aperture stop 800, a first lens element 810, a second lens element 820, a third lens element 830, a fourth lens element 840, a fifth lens element 850, a sixth lens element 860, an IR-bandstop filter 880, an image plane 890, and an image sensing device 892.
The first lens element 810 has positive refractive power and it is made of plastic material. The first lens element 810 has a convex object-side surface 812 and a concave image-side surface 814, both of the object-side surface 812 and the image-side surface 814 are aspheric, and the image-side surface 814 has an inflection point
The second lens element 820 has negative refractive power and it is made of plastic material. The second lens element 820 has a concave object-side surface 822 and a concave image-side surface 824, and both of the object-side surface 822 and the image-side surface 824 are aspheric. The image-side surface 824 has two inflection points.
The third lens element 830 has negative refractive power and it is made of plastic material. The third lens element 830 has a convex object-side surface 832 and a concave image-side surface 834, and both of the object-side surface 832 and the image-side surface 834 are aspheric. The object-side surface 832 and the image-side surface 834 both have an inflection point.
The fourth lens element 840 has positive refractive power and it is made of plastic material. The fourth lens element 840 has a concave object-side surface 842 and a convex image-side surface 844, and both of the object-side surface 842 and the image-side surface 844 are aspheric. The object-side surface 842 has three inflection points.
The fifth lens element 850 has positive refractive power and it is made of plastic material. The fifth lens element 850 has a convex object-side surface 852 and a convex image-side surface 854, and both of the object-side surface 852 and the image-side surface 854 are aspheric. The object-side surface 852 has three inflection points and the image-side surface 854 has an inflection point.
The sixth lens element 860 has negative refractive power and it is made of plastic material. The sixth lens element 860 has a concave object-side surface 862 and a concave image-side surface 864. The object-side surface 862 has two infection points and the image-side surface 864 has an inflection point. Hereby, the back focal length is reduced to miniaturize the lens element effectively. In addition, the angle of incident with incoming light from an off-axis view field can be suppressed effectively and the aberration in the off-axis view field can be corrected further.
The IR-bandstop filter 880 is made of glass material without affecting the focal length of the optical image capturing system and it is disposed between the sixth lens element 860 and the image plane 890.
In the optical image capturing system of the eighth embodiment, a sum of focal lengths of all lens elements with positive refractive power is ΣPP. The following relations are satisfied: ΣPP=12.785 mm and f5/ΣPP=0.10. Hereby, it is favorable for allocating the positive refractive power of a single lens element to other positive lens elements and the significant aberrations generated in the process of moving the incident light can be suppressed.
In the optical image capturing system of the sixth embodiment, a sum of focal lengths of all lens elements with negative refractive power is ΣNP. The following relations are satisfied: ΣNP=−112.117 mm and f6/ΣNP=0.009. Hereby, it is favorable for allocating the negative refractive power of a single lens element to other negative lens elements.
Please refer to the following Table 15 and Table 16.
The detailed data of the optical image capturing system of the eighth Embodiment is as shown in Table 15.
