摘要
Abstract
For shortwave infrared transmission imaging systems using cold optics,as the difference between fabrication and alignment temperature of optical components and supporting structure with operation temperature is large,variety of changes in geometry for different optical components would lead to position error for optical components,or even be destroyed.Aiming at the requirements of optical machine structural design for low-temperature infrared system,a set of shortwave infrared imaging system is designed and fabricated according to principles of uniformity and non-adjustment.In this pater,45° slope is designed on the mating surfaces of lens and supporting structure to fully adapt thermal expansion and cold contraction of optical elements and their supporting structure in process of temperature change.At last,it is verified by experiments that this optical supporting scheme has good imaging effect in low temperature condition of 80 K,and this paper provides high reference value for infrared optical machine structural design in large temperature difference.关键词
