摘要
目前空间光学相机用反射镜大多采用脆性材料,所以结构简单的胶接方式比较适合反射镜的固定。但是如何控制胶接质量、降低或消除由胶接应力引起的反射镜镜面变形显得至关重要。针对空间光学相机中常用的反射镜光学环氧胶胶接,通过合理确定胶层参数、采用相应手段控制胶层厚度以及采用合理的光学环氧胶固化工艺,降低了反射镜胶接时的胶接应力,保证了反射镜面形在胶接前后维持不变。通过试验验证了该胶接方案的合理性和可行性。
Currently,since most of mirrors for space optical cameras are made of brittle materials,they are suitable to be fixed by cementation with simple configuration.However,how to control cementation quality and how to reduce or remove the transmutation of the mirror due to the stress of cementation are very important.For the mirror optical epoxy glue cementation frequently used in space optical cameras,because the measures such as reasonable determination of cementation parameters,control of cementation thickness and use of proper optical epoxy glue technology are taken,the stress due to the cementation of the mirror is reduced and the surface figure of the mirror is kept unchanged before and after cementation.The test result shows that this cementation method is reasonable and feasible.
