摘要

为实现真空100 K低温环境中的红外设备测试，设计了一种离轴三反式的准直系统。该系统采用无热化设计，整机结构选用SiC材料，在镜体与支撑结构连接处采用C形开口胀销作为柔性结构，补偿连接结构的低温变形。系统整体除反射镜外，其余部分全部包裹在低温辐射冷板内。低热导绝热支撑结构在热传导链中起热屏蔽作用，实现系统的绝热支撑和快速制冷。在100 K低温环境下对单镜进行仿真分析，主、次、三镜的面形误差均小于λ/50；整机分析得到主、次、三镜的面形误差均不大于

/30。常温下系统各个视场波前差在

/14~

/8内，低温下系统视场波前差在

/8~

/7内，根据瑞利判据可认为波面无缺陷。当

=632.8 nm时，常温下系统在50 lp/mm频率的调制传递函数（Modulation Transfer Function，MTF）大于0.7；低温下的MTF大于0.6，满足系统在50 lp/mm MTF大于0.6的使用要求。仿真结果表明，准直系统可以在100 K真空环境中稳定输出平行光，满足低温红外设备的测试需求。在快速辐射制冷材料级实验中，历经18 h，温度稳定在130 K；历经30 h，SiC镜坯温度稳定在110 K。该实验验证了SiC反射镜快速辐射制冷的可行性。

Abstract

An off-axis three-mirror collimating optical system is designed to test the infrared equipment in a vacuum 100-K cryogenic environment. The system adopts athermal design， and the whole structure adopts SiC material. A C-shaped opening expansion sleeve is used as a flexible structure to compensate for low-temperature deformation at the connection between the mirror body and the support structure. The whole system is partially wrapped in a radiation cooling panel， except for the reflecting mirror. The low-thermal conductivity thermal insulation support structure plays a thermal shielding role in the heat conduction chain to realize the thermal insulation support and rapid refrigeration of the system. In the 100-K low-temperature environment， according to a system simulation analysis， the primary， secondary， and tertiary mirror wavefront error is

/50； an analysis of the whole structure indicates that the wavefront errors of the primary， secondary， and tertiary mirrors are ≤

/30. The wavefront error of each field of view of the system is in the range of

/14-

/8 at room temperature and in the range of

/8-

/7 at 100 K. According to the Rayleigh criterion， the wavefront is considered to be flawless. When

= 632.8 nm， the modulation transfer function （MTF） of the system at a 50 lp/mm frequency is

0.7 at room temperature； at a low temperature， the MTF is

0.6. Meet the system at 50 lp/mm greater than 0.6 use requirements. The results indicate that the collimating optical system can output parallel light stably in a 100-K vacuum environment to meet the test requirements of low-temperature infrared equipment. In a material level test of fast radiation cooling， the temperature of the SiC mirror blank is stable at 130 K after 18 h. After 30 h， the mirror blank temperature stabilizes at 110 K. The experiment verifies the feasibility of fast radiation cooling of the SiC mirror.
