Description

TECHNICAL FIELD

The present disclosure relates to the field of optical lens, and more particularly, to a camera optical lens suitable for handheld terminal devices such as smart phones or digital cameras and camera devices such as monitors or PC lenses.

BACKGROUND

With the emergence of smart phones in recent years, the demand for miniature camera lens is increasing day by day, but in general the photosensitive devices of camera lens are nothing more than Charge Coupled Device (CCD) or Complementary Metal-Oxide Semiconductor Sensor (CMOS sensor), and as the progress of the semiconductor manufacturing technology makes the pixel size of the photosensitive devices become smaller, plus the current development trend of electronic products towards better functions and thinner and smaller dimensions, miniature camera lenses with good imaging quality therefore have become a mainstream in the market.

In order to obtain better imaging quality, the lens that is traditionally equipped in mobile phone cameras adopts a three-piece or four-piece lens structure, or even five-piece or six piece lens structure. Also, with the development of technology and the increase of the diverse demands of users, and as the pixel area of photosensitive devices is becoming smaller and smaller and the requirement of the system on the imaging quality is improving constantly, a seven-piece lens structure gradually appears in lens designs. Although the common seven-piece lens has good optical performance, its settings on refractive power, lens spacing and lens shape still have some irrationality, which results in that the lens structure cannot achieve a high optical performance while satisfying design requirements for wide-angle and ultra-thin lenses having a big aperture.

DESCRIPTION OF EMBODIMENTS

The present disclosure will hereinafter be described in detail with reference to several exemplary embodiments. To make the technical problems to be solved, technical solutions and beneficial effects of the present disclosure more apparent, the present disclosure is described in further detail together with the figure and the embodiments. It should be understood the specific embodiments described hereby is only to explain the disclosure, not intended to limit the disclosure.

Embodiment 1

Referring to FIG. 1, the present disclosure provides a camera optical lens 10. FIG. 1 shows the camera optical lens 10 according to Embodiment 1 of the present disclosure. The camera optical lens 10 includes 7 lenses. Specifically, the camera optical lens 10 includes, from an object side to an image side, an aperture S1, a first lens L1, a second lens L2, a third lens L3, a fourth lens L4, a fifth lens L5, a sixth lens L6 and a seventh lens L7. An optical element such as a glass plate GF can be arranged between the seventh lens L7 and an image plane Si. The glass plate GF can be a glass cover plate or an optical filter. In other embodiments, the glass plate GF can be arranged at other positions.

In present embodiment, the first lens L1 has a positive refractive power, and has an object side surface being a convex surface and an image object surface being a concave surface; the second lens L2 has a negative refractive power, and has an object side surface being a convex surface and an image object surface being a concave surface; the third lens L3 has a positive refractive power, and has an object side surface being a convex surface and an image object surface being a concave surface; the fourth lens L4 has a positive refractive power, and has an object side surface being a convex surface and an image object surface being a convex surface; the fifth lens L5 has a negative refractive power, and has an object side surface being a concave surface and an image object surface being a convex surface; a sixth lens L6 has a positive refractive power, and has an object side surface being a convex surface and an image object surface being a concave surface; and the seventh lens L7 has a negative refractive power, and has an object side surface being a convex surface and an image object surface being a concave surface.

Here, a focal length of the camera optical lens 10 is defined as f in a unit of millimeter (mm), a focal length of the third lens L3 is defined as f3, and a focal length of the sixth lens L6 is defined as f6. The camera optical lens 10 should satisfy following conditions:

15.00≤f3/f  (1); and

2.50≤f6/f≤5.00  (2).

The condition (1) specifies a ratio of the focal length of the third lens L3 and the focal length of the camera optical lens 10. This leads to the appropriate distribution of the refractive power for the third lens L3, thereby facilitating improving the optical performance of the camera optical lens 10.

The condition (2) specifies a ratio of the focal length of the sixth lens L6 and the focal length of the camera optical lens 10. This leads to the appropriate distribution of the refractive power for the sixth lens L6, thereby facilitating correction of aberrations of the camera optical lens and thus improving the imaging quality.

In this embodiment, with the above configurations of the lenses including respective lenses (L1, L2, L3, L4, L5, L6 and L7) having different refractive powers, there is a specific relationship between focal lengths of the third lens L3 and the camera optical lens 10 and there is a specific relationship between focal lengths of the sixth lens L6 and the camera optical lens 10. This leads to the effective distribution of the refractive power of the third lens L3 and the refractive power of the sixth lens L6, thereby facilitating correction of aberrations of the camera optical lens. Thus, the camera optical lens can achieve a high optical performance while satisfying design requirements for wide-angle and ultra-thin lenses having a big aperture.

In this embodiment, the first lens L1 has a positive refractive power and a focal length of f1; the second lens L2 has a negative refractive power and a focal length of f2; the third lens L3 has a positive refractive power and a focal length of f3; the fourth lens L4 has a positive refractive power and a focal length of f4; and the fifth lens L5 has a negative refractive power and a focal length of f5, where f1, f2, f3, f4 and f5 satisfy the following condition of:

10.00≤|f1+f3+f4|/|f2+f5|≤20.00  (3).

The condition (3) specifies a ratio of an absolute value of a sum of the focal length f1 of the first lens L1, the focal length f3 of the third lens L3 and the focal length f4 of the fourth lens L4 to an absolute value of a sum of the focal length f2 of the second lens L2 and the focal length f5 of the fifth lens L5. This can facilitate improving the imaging quality of the camera optical lens.

In an example, a curvature radius of the object side surface of the third lens L3 is defined as R5 and a curvature radius of the image side surface of the third lens L3 is defined as R6, where R5 and R6 satisfy a condition of:

(R5+R6)/(R5−R6)≤−20.00  (4).

The condition (4) specifies a shape of the third lens L3. Within this range, a development towards wide-angle lenses having a big aperture can alleviate a deflection degree of light passing through the lens, thereby effectively reducing aberrations.

In an example, the focal length of the second lens L2 is defined as f2 in a unit of millimeter (mm), and f2 and f satisfy a condition of:

−15.00≤f2−f≤−11.00  (5).

The condition (5) specifies a difference between the focal length f2 of the second lens L2 and the focal lens f of the camera optical lens 10. This can facilitate improving the imaging quality of the camera optical lens.

In an example, a curvature radius of the object side surface of the fifth lens L5 is defined as R9 and a curvature radius of the image side surface of the fifth lens L5 is defined as R10, where R9 and R10 satisfy a condition of:

−10.00≤(R9+R10)/(R9−R10)≤−6.00  (6).

The condition (6) specifies a shape of the fifth lens. This can effectively correct aberrations caused by the first four lenses (L1, L2, L3 and L4) of the camera optical lens.

In an example, an on-axis thickness of the first lens L1 is defined as d1, an on-axis distance from the image side surface of the first lens L1 to the object side surface of the second lens L2 is defined as d2, and d1 and d2 satisfy a condition of:

9.00≤d1/d2≤12.00  (7).

The condition (7) specifies a ratio of the on-axis thickness of the first lens L1 to the on-axis distance from the image side surface of the first lens L1 to the object side surface of the second lens L2. This can facilitate processing and assembly of the lenses.

In addition, a surface of a lens can be set as an aspherical surface. The aspherical surface can be easily formed into a shape other than the spherical surface, so that more control variables can be obtained to reduce the aberration, thereby reducing the number of lenses and thus effectively reducing a total length of the camera optical lens according to the present disclosure. In an embodiment of the present disclosure, both an object side surface and an image side surface of each lens are aspherical surfaces.

It should be noted that the first lens L1, the second lens L2, the third lens L3, the fourth lens L4, the fifth lens L5, the sixth lens L6 and the seventh lens L7 that constitute the camera optical lens 10 of the present embodiment have the structure and parameter relationships as described above, and therefore, the camera optical lens 10 can reasonably distribute the refractive power, the surface shape, the material, the on-axis thickness and the like of each lens, and thus correct various aberrations. The camera optical lens 10 has Fno≤1.70. A total optical length from the object side surface of the first lens to an image plane of the camera optical lens along an optic axis (TTL) and an image height (IH) of the camera optical lens 10 satisfy a condition of TTL/IH≤1.56. The field of view (FOV) of the camera optical lens 10 satisfies FOV≥76.6 degrees. This can achieve a high optical performance while satisfying design requirements for wide-angle and ultra-thin lenses having a big aperture.

In an example, inflexion points and/or arrest points can be arranged on the object side surface and/or image side surface of the lens, so as to satisfy the demand for the high quality imaging. The description below can be referred to for specific implementations.
