Abstract
A secondary imaging convergence system is designed for a cooled infrared optical system with three Germanium lenses. An optimal design method for low stray radiation is proposed. Compared with the traditional method, stray light analysis shows that the new design method can suppress stray radiation by 23.87% more than the traditional method.
