Abstract:In view of the problem that the imaging quality of the large-aperture and long-focal length infrared optical system is sensitive to temperature changes.In this paper,we propose an idea of combining athermalization design with catadioptric optical system,and a large-aperture long-focal length catadioptric infrared optical system is designed by this idea.According to the influence of each parameter by environmental changes,the system optical power is allocated reasonably.Select the appropriate infrared lens mate… Show more
