z=ch.sup.2/[1+[1(k+1)c.sup.2h.sup.2].sup.0.5]+A4h.sup.4+A6h.sup.6+A8h.sup.8+A10h.sup.10+A12h.sup.12+A14h.sup.14+A16h.sup.16+A18h.sup.18+A20h.sup.20+ . . .(1),

where z is a position value of the position along the optical axis and at the height h which reference to the surface apex; 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.

[0085] In the optical image capturing system provided by the present invention, the lenses may be made of glass or plastic. If plastic material is adopted to produce the lenses, the cost of manufacturing will be lowered effectively. If lenses are made of glass, the heat effect can be controlled and the designed space arranged for the refractive power of the optical image capturing system can be increased. Further, the object side and the image side of the first through sixth lenses may be aspheric, so as to obtain more control variables. Compared with the usage of traditional lens element made of glass, the number of lens elements used can be reduced and the aberration can be eliminated. Thus, the total height of the optical image capturing system can be reduced effectively.

[0086] In addition, in the optical image capturing system provided by the present invention, if the lens has a convex surface, the surface of the lens adjacent to the optical axis is convex in principle. If the lens has a concave surface, the surface of the lens adjacent to the optical axis is concave in principle.

[0087] The optical image capturing system of the present invention can be adapted to the optical image capturing system with automatic focus if required. With the features of a good aberration correction and a high quality of image formation, the optical image capturing system can be used in various application fields.

[0088] The optical image capturing system of the present invention can include a driving module according to the actual requirements. The driving module may be coupled with the lenses to enable the lenses producing displacement. The 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 distortion frequency owing to the vibration of the lens while shooting.

[0089] 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 according to the actual requirement. The light filter element may be made by coating at least one surface of the specific lens characterized of the filter function, and alternatively, may be made by the lens per se made of the material which is capable of filtering short wavelength.

[0090] 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), it is helpful to decrease the required incident angle to focus rays on the image plane. In addition to aiding 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.

The Third Embodiment (Embodiment 3)

[0170] Please refer to FIG. 3A, FIG. 3B and FIG. 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 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 third embodiment of the present invention. FIG. 3C 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 third embodiment of the present invention. As shown in FIG. 3A, in order from an object side to an image side, the optical image capturing system 30 includes a first lens 310, a second lens 320, a third lens 330, an aperture stop 300, a fourth lens 340, a fifth lens 350, a sixth lens 360, an IR-bandstop filter 380, an image plane 390, and an image sensing device 392.

[0171] The first lens 310 has negative refractive power and is made of glass. The first lens 310 has a convex object side 312 and a concave image side 314. Both of the object side 312 and the image side 314 of the first lens 310 are spherical.

[0172] The second lens 320 has negative refractive power and is made of plastic. The second lens 320 has a convex object side 322 and a concave image side 324. Both of the object side 322 and the image side 324 of the second lens 320 are aspheric.

[0173] The third lens 330 has positive refractive power and is made of plastic. The third lens 330 has a concave object side 332 and a convex image side 334. Both of the object side 332 and the image side 334 of the third lens 330 are aspheric.

[0174] The fourth lens 340 has positive refractive power and is made of plastic. The fourth lens 340 has a convex object side 342 and a convex image side 344. Both of the object side 342 and the image side 344 of the fourth lens 340 are aspheric. The object side 342 of the fourth lens 340 has one inflection point.

[0175] The fifth lens 350 has positive refractive power and is made of plastic. The fifth lens 350 has a convex object side 352 and a convex image side 354. Both of the object side 352 and the image side 354 of the fifth lens 350 are aspheric. The object side 352 of the fifth lens 350 has one inflection point.

[0176] The sixth lens 360 has negative refractive power and is made of plastic. The sixth lens 360 has a concave object side 362 and a concave image side 364. Both of the object side 362 and the image side 364 of the sixth lens 360 are aspheric. The image side 364 of the sixth lens 360 has one inflection point. Hereby, the back focal length is reduced to miniaturize the lens 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.

[0177] The IR-bandstop filter 380 is made of glass without affecting the focal length f of the optical image capturing system 30 and is disposed between the sixth lens 360 and the image plane 390.

[0178] Please refer to the following Table 5 and Table 6.

[0179] The detailed data of the optical image capturing system 30 of the third embodiment is as shown in Table 5.

[0186] The first lens 410 has negative refractive power and is made of glass. The first lens 410 has a convex object side 412 and a concave image side 414. Both of the object side 412 and the image side 414 of the first lens 410 are aspheric.

[0187] The second lens 420 has negative refractive power and is made of glass. The second lens 420 has a convex object side 422 and a concave image side 424.

[0188] The third lens 430 has positive refractive power and is made of plastic. The third lens 430 has a concave object side 432 and a convex image side 434. Both of the object side 432 and the image side 434 of the third lens 430 are aspheric.

[0189] The fourth lens 440 has positive refractive power and is made of plastic. The fourth lens 440 has a convex object side 442 and a convex image side 444. Both of the object side 442 and the image side 444 of the fourth lens 440 are aspheric. The object side 442 of the fourth lens 440 has one inflection point.

[0190] The fifth lens 450 has positive refractive power and is made of plastic. The fifth lens 450 has a concave object side 452 and a convex image side 454. Both of the object side 452 and the image side 454 of the fifth lens 450 are aspheric.

[0191] The sixth lens 460 has negative refractive power and is made of plastic. The sixth lens 460 has a concave object side 462 and a convex image side 464. Both of the object side 462 and the image side 464 of the sixth lens 460 are aspheric. Both of the object side 462 and the image side 464 of the sixth lens 460 have one inflection point. Hereby, the back focal length is reduced to miniaturize the lens 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.

[0192] The IR-bandstop filter 480 is made of glass without affecting the focal length f of the optical image capturing system 40 and is disposed between the sixth lens 460 and the image plane 490.

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 invention. 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 invention. As shown in FIG. 5A, in order from an object side to an image side, the optical image capturing system 50 includes a first lens 510, a second lens 520, a third lens 530, an aperture stop 500, a fourth lens 540, a fifth lens 550, a sixth lens 560, an IR-bandstop filter 580, an image plane 590, and an image sensing device 592.

Both of the object side 512 and the image side 514 of the first lens 510 are aspheric. The object side 512 of the first lens 510 has one inflection point.

[0202] The second lens 520 has negative refractive power and is made of glass. The second lens 520 has a convex object side 522 and a concave image side 524. Both of the object side 522 and the image side 524 of the second lens 520 are spherical.

[0203] The third lens 530 has positive refractive power and is made of glass. The third lens 530 has a convex object side 532 and a concave image side 534. Both of the object side 532 and the image side 534 of the third lens 530 are spherical.

[0204] The fourth lens 540 has positive refractive power and is made of glass. The fourth lens 540 has a concave object side 542 and a convex image side 544. Both of the object side 542 and the image side 544 of the fourth lens 540 are spherical.

Both of the object side 562 and the image side 564 of the sixth lens 560 are spherical. Hereby, the back focal length is reduced to miniaturize the lens 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.

[0207] The IR-bandstop filter 580 is made of glass without affecting the focal length f of the optical image capturing system 50 and is disposed between the sixth lens 560 and the image plane 590.

The Sixth Embodiment (Embodiment 6)

[0215] Please refer to FIG. 6A, FIG. 6B and FIG. 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 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 sixth Embodiment of the present invention. FIG. 6C 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 sixth embodiment of the present invention. As shown in FIG. 6A, in order from an object side to an image side, the optical image capturing system 60 includes a first lens 610, a second lens 620, a third lens 630, an aperture stop 600, a fourth lens 640, a fifth lens 650, a sixth lens 660, an IR-bandstop filter 680, an image plane 690, and an image sensing device 692.

[0216] The first lens 610 has negative refractive power and is made of glass. The first lens 610 has a convex object side 612 and a concave image side 614. Both of the object side 612 and the image side 614 of the first lens 610 are spherical.

[0217] The second lens 620 has negative refractive power and is made of glass. The second lens 620 has a convex object side 622 and a concave image side 624. Both of the object side 622 and the image side 624 of the second lens 620 are spherical.

[0218] The third lens 630 has positive refractive power and is made of glass. The third lens 630 has a concave object side 632 and a convex image side 634. Both of the object side 632 and the image side 634 of the third lens 630 are aspheric.

[0219] The fourth lens 640 has positive refractive power and is made of glass. The fourth lens 640 has a concave object side 642 and a convex image side 644. Both of the object side 642 and the image side 644 of the fourth lens 640 are spherical.

[0220] The fifth lens 650 has positive refractive power and is made of glass. The fifth lens 650 has a convex object side 652 and a convex image side 654. Both of the object side 652 and the image side 654 of the fifth lens 650 are spherical.

[0221] The sixth lens 660 has positive refractive power and is made of glass. The sixth lens 660 has a convex object side 662 and a convex image side 664. Both of the object side 662 and the image side 664 of the sixth lens 660 are spherical. Hereby, the back focal length is reduced to miniaturize the lens 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.

[0222] The IR-bandstop filter 680 is made of glass without affecting the focal length f of the optical image capturing system 60 and is disposed between the sixth lens 660 and the image plane 690.

[0223] Please refer to the following Table 11 and Table 12.

[0224] The detailed data of the optical image capturing system 60 of the sixth Embodiment is as shown in Table 11.
