Abstract

In the traditional coaxial infrared television optical system, the central aperture of the infrared imaging system will be blocked by the television imaging system, which will cause obvious loss of luminous flux and decrease of diffraction limit. Because television imaging system is in the infrared channel, the infrared and television system size, configuration, performance, assembly will affect each other, which increases the design and assembly difficulty, as well as processing assembly and maintenance difficulty. In this paper, an off-axis infrared television composite optical system is designed. The infrared and television systems are decoupled from each other without interference. Two tilt lenses are added in front of the lens to correct the aberration of the television. The results show that the performance of off-axis infrared television composite optical system is better than that coaxial infrared television composite optical system.
