Industrial high-definition and low-distortion lens with F1.4 large aperture and 12 mm focal length

Abstract

The invention relates to an industrial high-definition and low-distortion lens with the F1.4 large aperture and the 12 mm focal length. The industrial high-definition and low-distortion lens comprisesan optical system arranged in a lens structure, and the optical system comprises a front lens group A, a diaphragm C and a rear lens group B which are sequentially arranged from front to back in thelight ray incident direction, wherein the front lens group A has the negative focal power, and the rear lens group B has the positive focal power; the front lens group is composed of a glued group formed by a negative crescent lens A1, a negative crescent lens A2, double convex lenses A3, a positive crescent lens A4, a positive crescent lens A5 and a positive crescent lens A6 in a compactly connected mode; and the rear lens group is composed of a glued group formed by double concave lenses B1 and double convex lenses B2 in a compactly connected mode, double convex lenses B3 and a positive crescent lens B4. The industrial lens is high in optical index, large in light transmission, low in distortion and high in resolution.

Description

technical field [0001] The invention relates to an F1.4 large aperture 12mm focal length high-definition low-distortion industrial lens. Background technique [0002] With the emergence of various high-resolution CCDs or CMOSs ​​on the market, although there are many lenses that can achieve high resolution and low distortion to match them, the actual imaging of more than 5 million lenses is not ideal. Because these lenses generally have problems such as small light transmission, low edge image quality, and high optical sensitivity, the overall imaging power of the lens is reduced. With the development of new technologies for industrial cameras, it meets the requirements of the machine vision inspection industry for high pixels. High definition is the current development trend of the industry. Therefore, maximum light, low distortion, and high resolution have become the mainstream configuration of industrial lenses.
