Problems solved by technology
However, the glass cover and the infrared filter lens occupy a considerable space in the camera module, and also cause the last lens to be far away from the image sensor, which limits the imaging performance of the lens and is not conducive to the miniaturization of the camera module.
Even if the glass cover and the infrared filter lens can be integrated into a single filter, it still limits the imaging performance of the lens and is not conducive to the miniaturization of the camera module

Embodiment Construction
[0037] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments.
[0038] see figure 2 and image 3 , the camera module 1 includes a lens 10 and an image sensor 20 .
[0039] The lens 10 has a lens barrel 11 , at least one front lens group 12 and at least one rear lens group 13 , and the front lens group 12 and the rear lens group 13 are both made of high temperature resistant materials. The rear lens group 13 is composed of a spherical or aspheric lens 131 and a filter transparent cover 132 . The filter transparent cover 132 has the function of filtering infrared light that cannot be seen by human eyes but can be sensed by the image sensor 22 . The filter light-transmitting cover 132 can be a flat glass 133, and a filter coating 134 is coated on the side of the flat glass 133 facing the image sensing element 22 to achieve the ...
