In the following embodiments, each lens of the optical photographic lens set can be made of glass or plastic, but is not limited to the materials listed in the embodiments. When the lens material is glass, the lens surface can be processed by grinding or molding; in addition, due to the temperature change resistance and high hardness of the glass material itself, the impact of environmental changes on the optical photographic lens set can be reduced, thereby extending the service life of the optical photographic lens set. When the lens material is plastic, it is beneficial to reduce the weight of the optical photographic lens set and reduce production costs.

In the embodiment of the present invention, each lens includes an object side facing the object being photographed and an image side facing the imaging plane. The surface shape of each lens is defined according to the shape of the surface in the region near the optical axis (near axis). For example, when the object side of a lens is described as convex, it means that the object side of the lens in the region near the optical axis is convex. That is, although the lens surface is described as convex in the embodiment, the surface may be convex or concave in the region far from the optical axis (off axis). The shape of each lens near the axis is determined by whether the radius of curvature of the surface is positive or negative. For example, if the radius of curvature of the object side of a lens is positive, the object side is convex; conversely, if the radius of curvature is negative, the object side is concave. For the image side of a lens, if the radius of curvature is positive, the image side is concave; conversely, if the radius of curvature is negative, the image side is convex.

In the embodiment of the present invention, the object side and image side of each lens can be spherical or aspherical surfaces. Using an aspherical surface on a lens helps to correct imaging aberrations of an optical photographic lens set such as spherical aberration, and reduce the number of optical lens elements used. However, the use of an aspherical lens will increase the cost of the entire optical photographic lens set. Although in the embodiment of the present invention, some optical lens surfaces use spherical surfaces, they can still be designed as aspherical surfaces as needed; or, some optical lens surfaces use aspherical surfaces, but they can still be designed as spherical surfaces as needed.

In the embodiment of the present invention, the total track length TTL (Total Track Length) of the optical imaging lens set is defined as the distance from the object side of the first lens of the optical imaging lens set to the imaging plane on the optical axis. The imaging height of the optical imaging lens set is called the maximum image height ImgH (Image Height); when an image sensing element is set on the imaging plane, the maximum image height ImgH represents half of the diagonal length of the effective sensing area of the image sensing element. In the following embodiments, the units of the curvature radius of all lenses, lens thickness, distance between lenses, total track length TTL of the lens set, maximum image height ImgH and focal length (Focal Length) are all expressed in millimeters (mm).

In addition, the object side surface and/or the image side surface of the second lens can be aspherical to improve spherical aberration.

The third lens has positive refractive power, and its object side surface is convex, and the image side surface can be convex or concave. The positive refractive power of the third lens is used to help converge light and correct astigmatism. The light divergence effect formed by the negative refractive power of the second lens and the light convergence effect of the third lens with positive refractive power can effectively reduce the spherical aberration of the optical photography lens group. In the embodiment of the present invention, the material of the third lens is plastic to reduce manufacturing costs and facilitate processing. In addition, the object side surface and/or the image side surface of the third lens are aspherical to meet the requirements of large aperture imaging quality.

The fourth lens has a refractive power, and its object side and image side surfaces can be convex or concave. In the embodiment of the present invention, the material of the fourth lens is plastic to reduce manufacturing costs and facilitate processing. In addition, the object side surface and/or image side surface of the fourth lens can be aspherical, which can make the light of the external field angle better converge at the required imaging height and meet the requirements of the image surface for the incident angle of the light.

The fifth lens has positive refractive power, and its object side surface is concave and its image side surface is convex. The positive refractive power of the fifth lens is used to help converge light and improve astigmatism.

In addition, the object side surface and/or the image side surface of the fifth lens can be aspherical to improve spherical aberration.

The sixth lens has positive refractive power. The object side surface of the sixth lens can be convex or concave, and the image side surface is convex. The positive refractive power of the sixth lens is helpful to converge light and improve astigmatism.
