Design of Compact Infrared Zoom Lens System
Infrared zoom lens system with cooled focal plane array (FPA) detector is widely used in military application.Relevant information about optical design can be got easily,but research on infrared zoom lens system with low cost and high image quality for commercial application is less.This paper design a Compact infrared zoom lens system with only four lenses,using an uncooled focal plane array (FPA) with 384 × 288 pixels with zoom ratio 3∶1.Because of large F number and less lenses,transmission of the whole zoom system is greatly improved.NETD and MRTD of infrared system will be satisfying by this compact design.There is no special surface such as diffractive surface,HOE in zoom lens system,and only Ge and Znse infrared materials are chosen which result in lower production cost of infrared zoom lens system for commercial applications.
