Abstract

A compact mid-wavelength infrared zoom camera with a zoom range of 15:1 and active athermalization has been developed. The moving groups for a wide zoom range are only two lens groups and moving machanisms of zoom are very simple, which allows easy access of opto-mechanical and electromechanical design. The final design adopts the configuration of reflective mirror fold, comprising of two mirrors and eleven refractive lenses made of two infrared materials such as germanium or silicon. The movement of the lens groups and the focal length of the system are smooth and continuous. The zoom lens has the advantages of simple structure, high image quality, simple moving lens groups, short zoom path and smooth zoom locus.
