粘接结构由于其结构简单、紧凑，应力分布均匀，温度适应性好等优点在光学仪器中应用广泛。对反射镜背部嵌套粘接金属衬套的支撑结构做了详细研究，选择弹性模量较低的粘接剂作为粘接结构用胶；从力学性能角度分析胶层厚度和粘接面积，从热学角度分析胶层的消热粘接厚度。对粘接结构对反射镜位置精度的影响进行分析，包括反射镜的偏心量和光轴方向的移动量。

Adhesive structure is widely used in optical instruments because of its simplicity, uniform stress distribution and good temperature adaptability. The back embedded adhesive structure for mirror support is analyzed theoretically. The principle for choosing adhesive is determined as choosing adhesive with low elastic modulus. The adhesive structure parameters including adhesive thickness and adhesive area are analyzed from mechanical and thermal properties. The adhesive structure′s effect on mirror position accuracy is analyzed, which includes mirror decenter and movement along optical axis.
