Problems solved by technology

[0002] At present, the optical wide-angle ultra-high-definition lenses used in security and machine vision generally have such shortcomings: the resolution of object details is insufficient, most of which are 20 million pixels, the system definition is low, and the amount of light is insufficient; the cost is high, for example, 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

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...
