摘要: 提出一种新的复合式腔镜结构，利用硅镜（钼镜）和铜镜的优点，避免它们的缺点，可以有效地减小热畸变。对钼、铜复合镜作了与硅镜的对比实验。实验结果表明钼、铜复合镜的热畸变比硅镜的约小一半。Abstract: A new complex structure of mirror cooled by phase change is presented in this paper. The advantage of silicon mirror and copper mirror was used and the defect of them was avoided simultaneously. Thermal distortion of mirror can be decreased effectively. Experiment of Comparing Mo-Cu complex mirror with Si mirror was done. It is shown that thermal distortion of Mo-Cu complex mirror is about half as much as thermal distortion of silicon mirror．
