长波红外制冷型光学系统超宽温消热差设计
Athermal Design of Cooled LWIR Optical System with Extensive Temperature Range
摘要
Abstract
Based on athermal design technologies of optical passive mode, this paper describes an example of a cooled long wave infrared optical system. This system adopts a linear IRFPA with 576 pixels. Compared with old linear IRFPA with 288 pixels, the larger pixel number results in a larger field of view with same parameters such as numerical aperture, focal length, etc. The F number is 1.6, the focal length is 100mm, and the FOV is 9.2°. This system has a 100% cold-shield-match. The result shows that the image quality of the system approaches the diffraction limit in the working temperature range - 50℃~+90℃ without focusing mechanism. So its athermal capability is improved.关键词
