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 optical image capturing module.

An equation of aspheric surface is

In the optical image capturing module, the lenses could be made of plastic or glass. The plastic lenses may reduce the weight and lower the cost of the optical image capturing module, and the glass lenses may control the thermal effect and enlarge the space for arrangement of the refractive power of the optical image capturing module. In addition, the opposite surfaces (object-side surface and image-side surface) of the first to the seventh lenses could be aspheric that could 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 optical image capturing module.

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 module of the present invention could be applied in a dynamic focusing optical image capturing module. 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 module of the present invention could further include a driving module to meet different demands, wherein the driving module could be coupled with the lenses to move the lenses. The driving module could be a voice coil motor (VCM), which is used to move the lens for focusing, or could 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 module of the present invention could be a light filter, which filters out light of wavelength shorter than 500 nm. Such effect could 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.

To meet different requirements, the image plane of the optical image capturing module in the present invention could be either flat or curved. If the image plane is curved (e.g., a sphere with a radius of curvature), the incidence angle required for focusing light on the image plane could be decreased, which is not only helpful to shorten the length of the optical image capturing module (TTL), but also helpful to increase the relative illuminance.

We provide several optical embodiments in conjunction with the accompanying drawings for the best understanding. In practice, the optical embodiments of the present invention could be applied to other structural embodiments.

The detail parameters of the first optical embodiment are listed in Table 1, in which the unit of the radius of curvature, thickness, and focal length are millimeter, and surface 0-16 indicates the surfaces of all elements in the system in sequence from the object side to the image side. Table 2 is the list of coefficients of the aspheric surfaces, in which k indicates the taper coefficient in the aspheric curve equation, and A1-A20 indicate the coefficients of aspheric surfaces from the first order to the twentieth order of each aspheric surface. The following optical embodiments have the similar diagrams and tables, which are the same as those of the first optical embodiment, so we do not describe it again. The definitions of the mechanism component parameters of the following optical embodiments are the same as those of the first optical embodiment.

Second Optical Embodiment

As shown in FIG. 3A and FIG. 3B, an optical image capturing module 20 of the second optical embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 210, a second lens 220, a third lens 230, an aperture 200, a fourth lens 240, a fifth lens 250, a sixth lens 260, a seventh lens 270, an IR-cut filter 280, an image plane 290, and an image sensor 292.

The first lens 210 has negative refractive power and is made of glass. An object-side surface 212 thereof, which faces the object side, is a convex spherical surface, and an image-side surface 214 thereof, which faces the image side, is a concave spherical surface.

The second lens 220 has negative refractive power and is made of glass. An object-side surface 222 thereof, which faces the object side, is a concave spherical surface, and an image-side surface 224 thereof, which faces the image side, is a convex spherical surface.

The third lens 230 has positive refractive power and is made of glass. An object-side surface 232, which faces the object side, is a convex spherical surface, and an image-side surface 234, which faces the image side, is a convex spherical surface.

The fourth lens 240 has positive refractive power and is made of glass. An object-side surface 242, which faces the object side, is a convex spherical surface, and an image-side surface 244, which faces the image side, is a convex spherical surface.

The fifth lens 250 has positive refractive power and is made of glass. An object-side surface 252, which faces the object side, is a convex spherical surface, and an image-side surface 254, which faces the image side, is a convex spherical surface.

The sixth lens 260 has negative refractive power and is made of glass. An object-side surface 262, which faces the object side, is a concave spherical surface, and an image-side surface 264, which faces the image side, is a concave spherical surface. Whereby, the incident angle of each view field entering the sixth lens 260 could be effectively adjusted to improve aberration.

The seventh lens 270 has negative 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 convex surface. It may help to shorten the back focal length to keep small in size, and 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 IR-cut filter 280 is made of glass and is disposed between the seventh lens 270 and the image plane 290. The IR-cut filter 280 gives no contribution to the focal length of the optical image capturing module.

The parameters of the lenses of the second optical embodiment are listed in Table 3 and Table 4.

Third Optical Embodiment

As shown in FIG. 4A and FIG. 4B, an optical image capturing module of the third optical 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 IR-cut filter 380, an image plane 390, and an image sensor 392.

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 spherical surface, and an image-side surface 314 thereof, which faces the image side, is a concave spherical 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 spherical surface, and an image-side surface 324 thereof, which faces the image side, is a convex spherical surface.

The third lens 330 has positive refractive power and is made of plastic. An object-side surface 332 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 334 thereof, which faces the image side, is a convex aspheric surface. The image-side surface 334 has an inflection point.

The fourth lens 340 has negative refractive power and is made of plastic. An object-side surface 342, which faces the object side, is a concave aspheric surface, and an image-side surface 344, which faces the image side, is a concave aspheric surface. The image-side surface 344 has an inflection point.

The fifth lens 350 has positive refractive power and is made of plastic. An object-side surface 352, which faces the object side, is a convex aspheric surface, and an image-side surface 354, which faces the image side, is a convex aspheric surface.

The sixth lens 360 has negative refractive power and is made of plastic. An object-side surface 362, which faces the object side, is a convex aspheric surface, and an image-side surface 364, which faces the image side, is a concave aspheric surface. The object-side surface 362 has an inflection point, and the image-side surface 364 has an inflection point. It may help to shorten the back focal length to keep small in size. Whereby, the incident angle of each view field entering the sixth lens 360 could be effectively adjusted to improve aberration.

The IR-cut filter 380 is made of glass and is disposed between the sixth lens 360 and the image plane 390. The IR-cut filter 390 gives no contribution to the focal length of the optical image capturing module.

The parameters of the lenses of the third optical embodiment are listed in Table 5 and Table 6.

Fourth Optical Embodiment

As shown in FIG. 5A and FIG. 5B, an optical image capturing module 40 of the fourth optical 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, an aperture 400, a third lens 430, a fourth lens 440, a fifth lens 450, an IR-cut filter 480, an image plane 490, and an image sensor 492.

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 spherical surface, and an image-side surface 414 thereof, which faces the image side, is a concave spherical surface.

The second lens 420 has negative refractive power and is made of plastic. An object-side surface 422 thereof, which faces the object side, is a concave aspheric surface, and an image-side surface 424 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 422 has an inflection point.

The third lens 430 has positive refractive power and is made of plastic. An object-side surface 432 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 434 thereof, which faces the image side, is a convex aspheric surface. The object-side surface 432 has an inflection point.

The fourth lens 440 has positive refractive power and is made of plastic. An object-side surface 442, which faces the object side, is a convex aspheric surface, and an image-side surface 444, which faces the image side, is a convex aspheric surface. The object-side surface 442 has an inflection point.

The fifth lens 450 has negative refractive power and is made of plastic. An object-side surface 452, which faces the object side, is a concave aspheric surface, and an image-side surface 454, which faces the image side, is a concave aspheric surface. The object-side surface 452 has two inflection points. It may help to shorten the back focal length to keep small in size.

The IR-cut filter 480 is made of glass and is disposed between the fifth lens 450 and the image plane 490. The IR-cut filter 480 gives no contribution to the focal length of the optical image capturing module.

The parameters of the lenses of the fourth optical embodiment are listed in Table 7 and Table 8.

Sixth Optical Embodiment

As shown in FIG. 7A and FIG. 7B, an optical image capturing module of the sixth optical embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 610, an aperture 600, a second lens 620, a third lens 630, an IR-cut filter 670, an image plane 680, and an image sensor 690.

The first lens 610 has positive refractive power and is made of plastic. An object-side surface 612, which faces the object side, is a convex aspheric surface, and an image-side surface 614, which faces the image side, is a concave aspheric surface.

The second lens 620 has negative refractive power and is made of plastic. An object-side surface 622 thereof, which faces the object side, is a concave aspheric surface, and an image-side surface 624 thereof, which faces the image side, is a convex aspheric surface. The image-side surface 624 has an inflection point.

The third lens 630 has positive refractive power and is made of plastic. An object-side surface 632, which faces the object side, is a convex aspheric surface, and an image-side surface 634, which faces the image side, is a concave aspheric surface. The object-side surface 632 has two inflection points, and the image-side surface 634 has an inflection point.

The IR-cut filter 670 is made of glass and is disposed between the third lens 630 and the image plane 680. The IR-cut filter 670 gives no contribution to the focal length of the optical image capturing module.

The parameters of the lenses of the sixth optical embodiment are listed in Table 11 and Table 12.
