High-resolution and high-illuminance machine vision system and manufacturing method thereof

The invention provides a high-resolution and high-illumination machine vision system and a manufacturing method thereof. A front lens group A, a diaphragm, a rear lens group B and flat protective glass are sequentially arranged in an optical system of a lens in the incident direction of light from left to right. The front lens group A comprises a crescent lens A1 having a positive focal power, a crescent lens A2 having a positive focal power, and a crescent lens A3 having a negative focal power, which are successively arranged. The rear lens group B sequentially comprises a biconcave lens B1 with negative focal power, a crescent lens B2 with positive focal power, a biconvex lens B3 with positive focal power and a crescent lens B4 with positive focal power; the focal power of the front lensgroup A of the optical system is negative, and the focal power of the rear lens group B of the optical system is positive. According to the system, the structure is simple and attractive, the resolution is high, and the illu
