High-resolution single-unit mobile industrial camera lens

The utility model relates to a high-resolution single-unit mobile industrial camera lens. A front group A with negative focal power, an iris diaphragm C and a rear group B with positive focal power are sequentially arranged along the incident direction of light from left to right in an optical system of the lens, the front group A is sequentially provided with a positive meniscus lens A-1, a positive meniscus lens A-2 and a negative meniscus lens A-3, and the rear group B is sequentially provided with a gluing group formed by tightly connecting a biconcave lens B-1 and a biconcave lens B-2, a biconcave lens B-3 and a positive meniscus lens B-4. The high-resolution single-unit mobile industrial camera lens has the characteristics of high resolution, large target surface, low distortion, small close-up distance and the like and can be matched with a high-definition CCD or CMOS camera, high-definition video shooting can be realized, clear imaging with the close-up distance of 0.3m can be realized, and the distortion rate is less than 1 percent.
