First lens 10, second lens 20, the 3rd lens 30, the 4th lens 40 and the 5th lens 50 all can make of plastic material.Like this, if all lens 10,20,30,40,50 make by plastic material, then can reduce the manufacturing expense of camera lens module 100, and the batch production of camera lens module 100 may be conducive to.And, if make each lens 10,20,30,40,50 with plastic material, then because the processing ratio of lens surface S1, S2, S3, S4, S5, S6, S7, S8, S9, S10 is easier to, therefore lens surface can be formed as sphere or aspheric surface.

First lens 10 can be configured in camera lens module 100 closest to object side.

First lens 10 can have positive refracting power generally.Further, in the first lens 10, first surface S1 can have the shape protruded towards object side, and second surface S2 can have recessed shape.And if then illustrate, first surface S1 can be convex and second surface S2 can be concavity.

Second lens 20 can be configured at the rear (direction, image side) of the first lens 10.Second lens 20 can have negative refracting power generally, and can be made by plastic material identically with the first lens 10.

The first surface S3 of the second lens 20 can have the shape protruded towards object side, and second surface S4 can have recessed shape.Further, the second lens 20 can have at least one aspheric surface.Such as, at least one surface in the first surface S3 of the second lens 20 and second surface S4 can be aspheric surface.But as required, the first surface S3 of the second lens 20 and second surface S4 can be aspheric surface.

Second lens 20 can have the abbe number (abbe number) meeting mathematical expression 1.

[mathematical expression 1]

ν2<40

Wherein, ν 2 is the abbe number (abbe number) of the second lens.

Like this, if the abbe number of the second lens 20 is less than 40, then the chromatic aberation caused by the first lens 10 can effectively be corrected.At this, if the abbe number of the second lens 20 is more than 40, then because the deviation between the abbe number of the first lens 10 and the abbe number of the second lens 20 reduces (abbe number of the first lens 10 is generally 50 ~ 60), the chromatic aberration correction effect therefore by means of the second lens 20 may reduce.Therefore, as advised in mathematical expression 1, preferably the abbe number of the second lens 20 is designed to less than 40.The abbe number of the second lens 20 can be 20 ~ 30.

3rd lens 30 can be configured at the rear of the second lens 20.3rd lens 30 can have positive refracting power generally, and can be made by plastic material.But as required, the 3rd lens 30 can have negative refracting power.

The first surface S5 of the 3rd lens 30 can have recessed shape, and second surface S6 can have the shape protruded towards image side.Wherein, the first surface S5 of the 3rd lens 30 optionally can have the shape (Fig. 5 with reference to the 3rd embodiment) protruded towards object side.

On the other hand, aforesaid second lens 20 and the 3rd lens 30 can meet mathematical expression 2.

[mathematical expression 2]

$-3.0<\frac{f3}{f2}<-0.3$

Wherein, f2 is the focal length [mm] of the second lens 20, and f3 is the focal length [mm] of the 3rd lens 30.

If the value of f3/f2 is below the lower limit based on mathematical expression 2 in camera lens module, then may make the making difficulty of the second lens due to the refracting power grow of the second lens.In like manner, if the value of f3/f2 is more than the higher limit based on mathematical expression 2 in camera lens module, then may make the making difficulty of the 3rd lens due to the refracting power grow of the 3rd lens.

Therefore, in order to the batch production of camera lens module, preferably meet the condition based on mathematical expression 2.

4th lens 40 are configurable in the rear of the 3rd lens 30.4th lens 40 can have negative refracting power, and can be made by plastic material.

[mathematical expression 4]

$\frac{f4}{f1}<-5.0$

Wherein, f1 is the focal length [mm] of the first lens, and f4 is the focal length [mm] of the 4th lens.

Mathematical expression 4 can be the qualifications of the refracting power for limiting the 4th lens.Namely, if the value of f4/f1 is more than the higher limit of mathematical expression 4, then the resolution of camera lens module 100 may be caused to reduce because the refracting power in camera lens module shared by the 4th lens 40 strengthens, or make the total length of camera lens module 100 (that is, the length of whole optical system) elongated.

[mathematical expression 5]

$\frac{f4}{f}<-3.0$

Wherein, f is the focal length [mm] of whole camera lens module, and f4 is the focal length [mm] of the 4th lens.

Identical with mathematical expression 4, mathematical expression 5 also can be the qualifications of the refracting power for limiting the 4th lens.Namely, if the value of f4/f is more than the higher limit of mathematical expression 5, then the resolving power of camera lens module 100 may be weakened due to refracting power (negative) grow in camera lens module shared by the 4th lens 40, or cause the focal length of whole camera lens module become too short and be difficult to realize distortion correction (or the visual angle of camera lens module may be made to become excessive and cause distortion phenomenon).

Therefore, in order to reduce the total length of camera lens module 100, preferably mathematical expression 4 and mathematical expression 5 are all met.

5th lens 50 are configurable in the rear of the 4th lens 40.5th lens 50 can have negative refracting power, and can be made by plastic material.

The first surface S9 of the 5th lens 50 can have and to protrude and in the recessed shape of the peripheral part of optical axis C-C to object side in the part crossing with optical axis C-C.In addition, the second surface S10 of the 5th lens 50 can have in the recessed and shape that is that protrude at the peripheral part of optical axis C-C of the part crossing with optical axis C-C.That is, the first surface S9 of the 5th lens 50 and second surface S10 can form the more than one point of inflexion.

Filter part 60 can be configured at the rear of the 5th lens 50.Two surfaces of filter part 60 can be all planes, and can be made by the material outside plastics.Such as, filter part 60 can be made by glass material.

Filter part 60 can intercept infrared ray.For this reason, at least one of filter part 60 can attach infrared ray (IR:infrared ray) anti-dazzling screen or coating infrared ray photomask on the surface.In addition, filter part 60 is for omitting according to the kind of camera lens module 100.

Imageing sensor 70 is configurable in the rear of filter part 60.

The picture of the subject by the incidence of each lens 10,20,30,40,50 can be transformed to electric signal by imageing sensor 70.Imageing sensor 70 can use CCD(Charge-coupled Device, charge coupled cell) imageing sensor, CMOS(Complementary Metal Oxide Semiconductor, complementary metal oxide semiconductor (CMOS)) imageing sensor, and wafer-level package (CSP:ChipScale Package) form can be made as.

The configurable front in the first lens 10 of aperture (not shown) or be configured between the first lens 10 and the second lens 20.But aperture can be omitted as required.

The camera lens module 100 of such formation can meet mathematical expression 6.

[mathematical expression 6]

$0.5<\frac{\mathrm{TL}}{f}<2.0$

Wherein, TL is the length (length [mm] from the first surface S1 of the first lens to the image planes of imageing sensor 70) of whole optical system, and f is the focal length [mm] of whole optical system.

Mathematical expression 6 can be the numerical value for the visual angle and length limiting camera lens module.That is, if the value of TL/f is below the lower limit of mathematical expression 6, then the visual angle of guaranteeing camera lens module 100 is difficult to.And if the value of TL/f is more than the higher limit of mathematical expression 6, be then difficult to because the length (i.e. TL) of camera lens module 100 is elongated make small-sized camera lens module 100.

In addition, aforesaid first lens 10 can be aspheric surfaces at least one surface of the 4th lens 40.The asphericity coefficient of these lens can utilize mathematical expression 7 to calculate.

[mathematical expression 7]

$z=\frac{{\mathrm{ch}}^2}{1+\mathrm{SQRT}[1-(1+K)c^2{h}^2]}+{\mathrm{Ah}}^4+{\mathrm{Bh}}^6+{\mathrm{Ch}}^8+{\mathrm{Dh}}^{10}+{\mathrm{Eh}}^{12}+{\mathrm{Fh}}^{14}$
