Problems solved by technology

A variety of machine vision lenses have been used in product inspection in the existing market, but the detection effect of many lenses is still at low resolution, and the range of detection object distance is small, so the detection effect is not ideal
Such lenses generally have problems such as large edge distortion, large structure size, and bulky volume.

Abstract

The invention relates to a high resolution machine vision optical system. In the optical system of a lens, a front group A, a diaphragm C, a rear group B and a flat glass are sequentially disposed along the incident direction of the light from the left to the right, wherein the front group A includes a meniscus lens A1 having a positive refractive power, a meniscus lens A2 having a negative refractive power, a meniscus lens A3 having a negative refractive power, a double-concave negative lens A4, a double-convex positive lens A5 and a double-convex positive lens A6, and the rear group B includes a double-concave negative lens B1, a double-convex positive lens B2, a double-convex positive lens B3 and a double-convex positive lens B4. The optical system has low sensitivity and small distortion and can maintain high-resolution imaging within a certain object distance range.

Description

technical field [0001] The invention relates to a high-resolution machine vision optical system. Background technique [0002] Machine vision is an important branch of the field of artificial intelligence. Machine vision lenses can replace human eyes to detect products, and realize the judgment function through the cooperation of algorithms. A variety of machine vision lenses have been used in product inspection in the existing market, but the detection effect of many lenses is still low-resolution, and the range of detection object distance is small, so the detection effect is not ideal. Such lenses generally have problems such as large edge distortion, large structural size, and bulky volume. Contents of the invention [0003] The object of the present invention is to provide a high-resolution machine vision optical system with a simple structure for the above disadvantages. [0004] The technical solution of the present invention is a high-resolution machine vision op...
