Eight-megapixel ultra-high-resolution wide-angle optical lens

Abstract

The invention relates to an eight-megapixel ultra-high-resolution wide-angle optical lens. An optical system of the lens comprises a front group A, a diaphragm C, a rear group B and a piece of plate glass L14. The front group A is sequentially provided with a meniscus positive lens L1, a meniscus negative lens L2, a meniscus negative lens L3, a biconcave negative lens L4, a first gluing group formed by tightly connection of a biconvex positive lens L5 and a meniscus negative lens L6, and a meniscus positive lens L7. The rear group B is sequentially provided with a second gluing group formed bya meniscus negative lens L8, a double-convex positive lens L9 and a meniscus negative lens L10, a double-convex positive lens L11, a meniscus positive lens L12, a meniscus negative lens L13 and plateglass L14. According to the invention, the optical structure of the lens is composed of 13 full-glass spherical lenses; no aspheric surface exists; and the cost is low and the assembling is easy. Theeight-megapixel ultra-high-resolution wide-angle optical lens has advantages of ultra-high resolution, large light flux and large field angle; the eight-megapixel imaging requirement is met; and theeight-megapixel ultra-high-resolution wide-angle optical lens can be specially used for capturing object details.

Description

technical field [0001] The invention relates to an 80 million-pixel ultra-high-resolution wide-angle optical lens. Background technique [0002] At present, optical wide-angle ultra-high-definition lenses used in security and machine vision generally have such shortcomings: insufficient resolution of object details, most of which are 20 million pixels, low system definition, insufficient light transmission; high cost, such as in order to achieve ultra-high definition , And the use of glass aspheric surface increases the input cost, or sacrifices the amount of light to make the brightness of the measured object insufficient. SUMMARY OF THE INVENTION [0003] In view of this, the purpose of the present invention is to provide an 80 million-pixel ultra-high-resolution wide-angle optical lens with ultra-high resolution, large light flux, and large field of view, which meets the imaging requirements of 80 million pixels. [0004] The present invention adopts the following sche...
