Abstract

The invention discloses an integrated infrared dual-band 20X zoom optical system. The integrated infrared dual-band 20X zoom optical system is composed of a common front fixing set, a common zooming set, a common compensation set, a common rear fixing set, a beam splitter prism, a long-wave infrared light rear fixing set, a medium-wave infrared focal length compensation set and a medium-wave infrared light rear fixing set which are sequentially arranged from left to right along an optical axis, wherein the beam splitter prism is used for reflecting medium-wave infrared light and transmitting long-wave infrared light, the long-wave infrared light rear fixing set is arranged on a transmission optical path of the beam splitter prism, the medium-wave infrared focal length compensation set is arranged on a reflection optical path of the beam splitter prism. In the continuous zooming process, a difference value between corresponding focal lengths of dual bands is less than a difference value between corresponding focal depths of the dual bands, target information of the dual bands can be received by the same system without switching the optical paths, and problems existing in an existing dual-band system at present are solved.

Description

[0001] 【Technical field】

[0002] The invention belongs to the technical field of optical equipment, and in particular relates to an integrated infrared dual-band 20X zoom optical system.

[0003] 【Background technique】

[0004] With the rapid development of infrared thermal imaging technology and the increasingly complex application environment, the requirements for the detection range, detection synchronization and real-time performance of the zoom imaging optical system are getting higher and higher. Compared with infrared single-band fixed-focus, infrared single-band fixed-point zoom, and single-band small zoom ratio zoom optical systems, dual-band or even multi-band continuous zoom optical systems have greater advantages, and can have more observation channels. Within the range of distance, it is beneficial to find the target more quickly, obtain more comprehensive target information, and realize the continuous search of short focus and large field of view, and the precise...
