When at least one lens among the second to the sixth lenses has weak positive refractive power, it may share the positive refractive power of the first lens, and on the contrary, when at least one lens among the second to the sixth lenses has weak negative refractive power, it may fine turn and correct the aberration of the system.
In an embodiment, the seventh lens could have negative refractive power, and an image-side surface thereof is concave, it may reduce back focal length and size. Besides, the seventh lens can have at least an inflection point on at least a surface thereof, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

In an embodiment, the lenses of high Abbe number and the lenses of low Abbe number are arranged in an interlaced arrangement that could be helpful for correction of aberration of the system.
An equation of aspheric surface is

z=ch2/[1+[1(k+1)c2h2]0.5]+A4h4+A6h6+A8h8+A10h10+A12h12+A14h14+A16h16+A18h18+A20h20+ . . .  (1)

In the optical image capturing system, the lenses could be made of plastic or glass. The plastic lenses may reduce the weight and lower the cost of the system, and the glass lenses may control the thermal effect and enlarge the space for arrangement of the refractive power of the system. In addition, the opposite surfaces (object-side surface and image-side surface) of the first to the seventh lenses could be aspheric that can obtain more control parameters to reduce aberration. The number of aspheric glass lenses could be less than the conventional spherical glass lenses, which is helpful for reduction of the height of the system.
When the lens has a convex surface, which means that the surface is convex around a position, through which the optical axis passes, and when the lens has a concave surface, which means that the surface is concave around a position, through which the optical axis passes.
The optical image capturing system of the present invention could be applied in a dynamic focusing optical system. It is superior in the correction of aberration and high imaging quality so that it could be allied in lots of fields.
The optical image capturing system of the present invention could further include a driving module to meet different demands, wherein the driving module can be coupled with the lenses to move the lenses. The driving module can be a voice coil motor (VCM), which is used to move the lens for focusing, or can be an optical image stabilization (OIS) component, which is used to lower the possibility of having the problem of image blurring which is caused by subtle movements of the lens while shooting.
To meet different requirements, at least one lens among the first lens to the seventh lens of the optical image capturing system of the present invention can be a light filter, which filters out the light of a wavelength shorter than 500 nm. Such effect can be achieved by coating on at least one surface of the lens, or by using materials capable of filtering out short waves to make the lens.

The seventh lens 270 has positive refractive power and is made of glass. An object-side surface 272, which faces the object side, is a convex surface, and an image-side surface 274, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size.
The infrared rays filter 280 is made of glass and between the seventh lens 270 and the image plane 290. The infrared rays filter 280 gives no contribution to the focal length of the system.
In the second embodiment, the optical image capturing system of the second embodiment further satisfies ΣPP=59.4742 mm; and f3/ΣPP=0.3135, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.
The optical image capturing system of the second embodiment further satisfies ΣNP=−40.6915 mm; and f2/ΣNP=0.3764, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of one single lens to other negative lenses.
The parameters of the lenses of the second embodiment are listed in Table 3 and Table 4.

Third Embodiment
As shown in FIG. 3A and FIG. 3B, an optical image capturing system of the third embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 310, a second lens 320, a third lens 330, an aperture 300, a fourth lens 340, a fifth lens 350, a sixth lens 360, a seventh lens 370, an infrared rays filter 380, an image plane 390, and an image sensor 392. FIG. 3C is a transverse aberration diagram at 0.7 field of view of the third embodiment of the present application.
The first lens 310 has negative refractive power and is made of glass. An object-side surface 312 thereof, which faces the object side, is a convex surface, and an image-side surface 314 thereof, which faces the image side, is a concave surface.
The second lens 320 has negative refractive power and is made of glass. An object-side surface 322 thereof, which faces the object side, is a concave surface, and an image-side surface 324 thereof, which faces the image side, is a concave surface.
The third lens 330 has positive refractive power and is made of glass. An object-side surface 332 thereof, which faces the object side, is a convex surface, and an image-side surface 334 thereof, which faces the image side, is a convex surface.
The fourth lens 340 has positive refractive power and is made of glass. An object-side surface 342, which faces the object side, is a convex surface, and an image-side surface 344, which faces the image side, is a convex surface.
The fifth lens 350 has negative refractive power and is made of glass. An object-side surface 352, which faces the object side, is a concave surface, and an image-side surface 354, which faces the image side, is a concave surface.
The sixth lens 360 has positive refractive power and is made of glass. An object-side surface 362, which faces the object side, is a convex surface, and an image-side surface 364, which faces the image side, is a convex surface.
The seventh lens 370 has positive refractive power and is made of glass. An object-side surface 372, which faces the object side, is a convex surface, and an image-side surface 374, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, it may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.
The infrared rays filter 380 is made of glass and between the seventh lens 370 and the image plane 390. The infrared rays filter 390 gives no contribution to the focal length of the system.
In the third embodiment, the optical image capturing system of the third embodiment further satisfies ΣPP=58.4170 mm; and f3/ΣPP=0.2519, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.
The optical image capturing system of the third embodiment further satisfies ΣNP=−36.7034 mm; and f1/ΣNP=0.3625, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of one single lens to other negative lenses.
The parameters of the lenses of the third embodiment are listed in Table 5 and Table 6.

Fourth Embodiment
As shown in FIG. 4A and FIG. 4B, an optical image capturing system 40 of the fourth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 410, a second lens 420, a third lens 430, an aperture 400, a fourth lens 440, a fifth lens 450, a sixth lens 460, a seventh lens 470, an infrared rays filter 480, an image plane 490, and an image sensor 492. FIG. 4C is a transverse aberration diagram at 0.7 field of view of the fourth embodiment of the present application.
The first lens 410 has negative refractive power and is made of glass. An object-side surface 412 thereof, which faces the object side, is a convex surface, and an image-side surface 414 thereof, which faces the image side, is a concave surface.
The second lens 420 has negative refractive power and is made of glass. An object-side surface 422 thereof, which faces the object side, is a concave surface, and an image-side surface 424 thereof, which faces the image side, is a convex surface.
The third lens 430 has positive refractive power and is made of glass. An object-side surface 432 thereof, which faces the object side, is a convex surface, and an image-side surface 434 thereof, which faces the image side, is a concave surface.
The fourth lens 440 has positive refractive power and is made of glass. An object-side surface 442, which faces the object side, is a convex surface, and an image-side surface 444, which faces the image side, is a convex surface.
The fifth lens 450 has negative refractive power and is made of glass. An object-side surface 452, which faces the object side, is a concave surface, and an image-side surface 454, which faces the image side, is a concave surface.
The sixth lens 660 has positive refractive power and is made of glass. An object-side surface 462, which faces the object side, is a convex surface, and an image-side surface 464, which faces the image side, is a convex surface. Whereby, the incident angle of each field of view for the sixth lens can be effectively adjusted to improve aberration.
The seventh lens 470 has positive refractive power and is made of glass. An object-side surface 472, which faces the object side, is a convex surface, and an image-side surface 474, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, it may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.
The infrared rays filter 480 is made of glass and between the seventh lens 470 and the image plane 490. The infrared rays filter 480 gives no contribution to the focal length of the system.
In the fourth embodiment, the optical image capturing system of the fourth embodiment further satisfies ΣPP=58.1097 mm; and f3/ΣPP=0.3749, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.
The optical image capturing system of the fourth embodiment further satisfies ΣNP=−401.6122 mm; and f1/ΣNP=0.9628, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of the sixth lens 460 to other negative lenses.
The parameters of the lenses of the fourth embodiment are listed in Table 7 and Table 8.

Fifth Embodiment
As shown in FIG. 5A and FIG. 5B, an optical image capturing system of the fifth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 510, a second lens 520, a third lens 530, an aperture 500, a fourth lens 540, a fifth lens 550, a sixth lens 560, a seventh lens 570, an infrared rays filter 580, an image plane 590, and an image sensor 592. FIG. 5C is a transverse aberration diagram at 0.7 field of view of the fifth embodiment of the present application.
The first lens 510 has negative refractive power and is made of glass. An object-side surface 512, which faces the object side, is a convex surface, and an image-side surface 514, which faces the image side, is a concave surface.
The second lens 520 has negative refractive power and is made of glass. An object-side surface 522 thereof, which faces the object side, is a concave surface, and an image-side surface 524 thereof, which faces the image side, is a concave surface.
The third lens 530 has positive refractive power and is made of glass. An object-side surface 532, which faces the object side, is a convex surface, and an image-side surface 534, which faces the image side, is a convex surface.
The fourth lens 540 has positive refractive power and is made of glass. An object-side surface 542, which faces the object side, is a convex surface, and an image-side surface 544, which faces the image side, is a convex surface.
The fifth lens 550 has negative refractive power and is made of glass. An object-side surface 552, which faces the object side, is a concave surface, and an image-side surface 554, which faces the image side, is a concave surface.
The sixth lens 560 can have positive refractive power and is made of glass. An object-side surface 562, which faces the object side, is a convex surface, and an image-side surface 564, which faces the image side, is a convex surface. Whereby, the incident angle of each field of view for the sixth lens 560 can be effectively adjusted to improve aberration.
The seventh lens 570 has positive refractive power and is made of glass. An object-side surface 572, which faces the object side, is a convex surface, and an image-side surface 574, which faces the image side, is a convex surface. It may help to shorten the back focal length to keep small in size.
The infrared rays filter 580 is made of glass and between the seventh lens 570 and the image plane 590. The infrared rays filter 580 gives no contribution to the focal length of the system.
In the fifth embodiment, the optical image capturing system of the fifth embodiment further satisfies ΣPP=43.9477 mm; and f3/ΣPP=0.2544, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.
The optical image capturing system of the fifth embodiment further satisfies ΣNP=−26.1812 mm; and f1/ΣNP=0.4022, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of one single lens to other negative lenses.
The parameters of the lenses of the fifth embodiment are listed in Table 9 and Table 10.

Sixth Embodiment
As shown in FIG. 6A and FIG. 6B, an optical image capturing system of the sixth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 610, a second lens 620, a third lens 630, an aperture 600, a fourth lens 640, a fifth lens 650, a seventh lens 660, a seventh lens 670, an infrared rays filter 680, an image plane 690, and an image sensor 692. FIG. 6C is a transverse aberration diagram at 0.7 field of view of the sixth embodiment of the present application.
The first lens 610 has negative refractive power and is made of glass. An object-side surface 612, which faces the object side, is a convex surface, and an image-side surface 614, which faces the image side, is a concave surface.
The second lens 620 has negative refractive power and is made of glass. An object-side surface 622 thereof, which faces the object side, is a concave surface, and an image-side surface 624 thereof, which faces the image side, is a convex surface.
The third lens 630 has positive refractive power and is made of glass. An object-side surface 632, which faces the object side, is a convex surface, and an image-side surface 634, which faces the image side, is a convex surface.
The fourth lens 640 has positive refractive power and is made of glass. An object-side surface 642, which faces the object side, is a convex surface, and an image-side surface 644, which faces the image side, is a convex surface.
The fifth lens 650 has negative refractive power and is made of glass. An object-side surface 652, which faces the object side, is a concave surface, and an image-side surface 654, which faces the image side, is a concave surface.
The sixth lens 660 can have positive refractive power and is made of glass. An object-side surface 662, which faces the object side, is a convex surface, and an image-side surface 664, which faces the image side, is a convex surface. Whereby, the incident angle of each field of view for the sixth lens 660 can be effectively adjusted to improve aberration.
The seventh lens 670 has positive refractive power and is made of glass. An object-side surface 672, which faces the object side, is a convex surface, and an image-side surface 674, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, it may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.
The infrared rays filter 680 is made of glass and between the seventh lens 670 and the image plane 690. The infrared rays filter 680 gives no contribution to the focal length of the system.
In the sixth embodiment, the optical image capturing system of the sixth embodiment further satisfies ΣPP=46.2045 mm; and f3/ΣPP=0.3229, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.
The optical image capturing system of the sixth embodiment further satisfies ΣNP=−97.9446 mm; and f1/ΣNP=0.8829, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of one single lens to the other negative lenses to avoid the significant aberration caused by the incident rays.
The parameters of the lenses of the sixth embodiment are listed in Table 11 and Table 12.

Seventh Embodiment
As shown in FIG. 7A and FIG. 7B, an optical image capturing system of the seventh embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 710, a second lens 720, a third lens 730, an aperture 700, a fourth lens 740, a fifth lens 750, a seventh lens 760, a seventh lens 770, an infrared rays filter 780, an image plane 790, and an image sensor 792. FIG. 7C is a transverse aberration diagram at 0.7 field of view of the seventh embodiment of the present application.
The first lens 710 has negative refractive power and is made of glass. An object-side surface 712, which faces the object side, is a convex surface, and an image-side surface 714, which faces the image side, is a concave surface.
The second lens 720 has negative refractive power and is made of glass. An object-side surface 722 thereof, which faces the object side, is a concave surface, and an image-side surface 724 thereof, which faces the image side, is a concave surface.
The third lens 730 has positive refractive power and is made of glass. An object-side surface 732, which faces the object side, is a convex surface, and an image-side surface 734, which faces the image side, is a convex surface.
The fourth lens 740 has positive refractive power and is made of glass. An object-side surface 742, which faces the object side, is a convex surface, and an image-side surface 744, which faces the image side, is a convex surface.
The fifth lens 750 has negative refractive power and is made of glass. An object-side surface 752, which faces the object side, is a convex surface, and an image-side surface 754, which faces the image side, is a convex surface.
The sixth lens 760 can have positive refractive power and is made of glass. An object-side surface 762, which faces the object side, is a concave surface, and an image-side surface 764, which faces the image side, is a convex surface. Whereby, the incident angle of each field of view for the sixth lens 760 can be effectively adjusted to improve aberration.
The seventh lens 770 has positive refractive power and is made of glass. An object-side surface 772, which faces the object side, is a convex surface, and an image-side surface 774, which faces the image side, is a convex surface. It may help to shorten the back focal length to keep small in size. In addition, it may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.
The infrared rays filter 780 is made of glass and between the seventh lens 770 and the image plane 790. The infrared rays filter 780 gives no contribution to the focal length of the system.
In the seventh embodiment, the optical image capturing system of the seventh embodiment further satisfies ΣPP=58.2236 mm; and f3/ΣPP=0.1720, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.
The optical image capturing system of the seventh embodiment further satisfies ΣNP=−33.2827 mm; and f1/ΣNP=0.2545, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of one single lens to the other negative lenses to avoid the significant aberration caused by the incident rays.
The parameters of the lenses of the sixth embodiment are listed in Table 13 and Table 14.

Eighth Embodiment
As shown in FIG. 8A and FIG. 8B, an optical image capturing system of the eighth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 810, a second lens 820, an aperture 800, a third lens 830, a fourth lens 840, a fifth lens 850, a seventh lens 860, a seventh lens 870, an infrared rays filter 880, an image plane 890, and an image sensor 892. FIG. 8C is a transverse aberration diagram at 0.7 field of view of the eighth embodiment of the present application.
The first lens 810 has negative refractive power and is made of glass. An object-side surface 812, which faces the object side, is a convex surface, and an image-side surface 814, which faces the image side, is a concave surface.
The second lens 820 has positive refractive power and is made of glass. An object-side surface 822 thereof, which faces the object side, is a concave surface, and an image-side surface 824 thereof, which faces the image side, is a convex surface.
The third lens 830 has positive refractive power and is made of glass. An object-side surface 832, which faces the object side, is a convex surface, and an image-side surface 834, which faces the image side, is a convex surface.
The fourth lens 840 has negative refractive power and is made of glass. An object-side surface 842, which faces the object side, is a concave surface, and an image-side surface 844, which faces the image side, is a concave surface.
The fifth lens 850 has positive refractive power and is made of glass. An object-side surface 852, which faces the object side, is a convex surface, and an image-side surface 854, which faces the image side, is a convex surface.
The sixth lens 860 can have negative refractive power and is made of glass. An object-side surface 862, which faces the object side, is a concave surface, and an image-side surface 864, which faces the image side, is a convex surface. Whereby, the incident angle of each field of view for the sixth lens 860 can be effectively adjusted to improve aberration.
The seventh lens 870 has positive refractive power and is made of glass. An object-side surface 872, which faces the object side, is a convex surface, and an image-side surface 874, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, it may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.
The infrared rays filter 880 is made of glass and between the seventh lens 870 and the image plane 890. The infrared rays filter 880 gives no contribution to the focal length of the system.
In the eighth embodiment, the optical image capturing system of the seventh embodiment further satisfies ΣPP=774.0381 mm; and f3/ΣPP=0.0067, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.
The optical image capturing system of the eighth embodiment further satisfies ΣNP=−23.6329 mm; and f1/ΣNP=0.3709, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of one single lens to the other negative lenses to avoid the significant aberration caused by the incident rays.
The parameters of the lenses of the sixth embodiment are listed in Table 15 and Table 16.
