Athermal Design for MW Infrared Dual Field-of-View Optical System
摘要
Abstract
A rotate-zoom optical system for medium wave 320 × 240 element IR FPA ( Focal Plane Arrays) detector is designed in this paper. The operating waveband of the system is 3.7～4.8 μm, and zoom ratio is 3×. The optical passive athermalization method is introduced to realize a high image quality in a wide temperature range of -40℃ ～60℃. Design result showed the rotate-zoom system has simple mechanism,compact structure, light weight, excellent image quality, and reliable performance within required temperature range. The optical system image quality is evaluated with the ZEMAX optical design software.关键词
