Wide-spectrum ultraviolet imager optical system based on material

Abstract

The invention discloses a wide-spectrum ultraviolet imager optical system based on a material, belongs to the technical field of ultraviolet detection, and is used for solving the problems that in the prior art, the number of lens materials in a wide-spectrum ultraviolet imager optical system is more than two, and lenses are not completely spherical surfaces, so that the difficulty of lens processing, detection and optical machine installation and adjustment is large, and the cost is high. The optical system comprises: a first lens and a second lens which are arranged on the central axis of the optical system in a spaced mode; a refraction-reflection mirror group and an optical filter which are sequentially arranged between the first lens and the second lens; and a detector which is arranged on the side, away from the optical filter, of the second lens, wherein the first lens, the second lens and the refraction-reflection mirror group are made of the same material, and the lenses are spherical surfaces, and the system has the advantages of being high in imaging quality, small in processing, detection and light machine adjustment difficulty and low in production cost.

Description

technical field [0001] The invention relates to the technical field of ultraviolet detection, in particular to an optical system of a wide-spectrum ultraviolet imager based on a material. Background technique [0002] As a mature technology, ultraviolet detection technology has been widely used in space atmospheric remote sensing detection, astronomical ultraviolet star observation, environmental monitoring, marine oil spill pollution monitoring, weapon warning, weapon early warning, and power line inspection. Human production and life are of great significance; [0003] The optical system is the core part of the ultraviolet imaging detection system, which directly determines the performance of the ultraviolet imaging detection system. Since there are few optical lens materials to choose from in the ultraviolet band, especially considering the physical and chemical properties of optical materials in practical applications, processing Performance and anti-radiation performan...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the optical system of the existing ultraviolet imager, especially the optical system of the wide-spectrum ultraviolet imager, has two or more types of optical lens materials, and the lens is not completely spherical, resulting in lens processing, detection and It is very difficult to assemble and adjust the optics, and a variety of lens materials will increase the cost accordingly;

[0005] Therefore, how to solve the situation that there are two or more optical lens materials in the optical system of the wide-spectrum ultraviolet imager in the prior art, and the lens is not completely spherical, which leads to great difficulties in lens processing, inspection, and optical-mechanical assembly. , the problem of high cost has become an important technical problem that those skilled in the art need to solve urgently
