摘要
以声光晶体TeO2为衬底, 设计并研制了1 300~3 400 nm波段超宽带减反射膜.从薄膜热应力理论出发, 建立膜层热应力受力示意图, 结合TeO2晶体的特性和力矩判定方法, 采用解析法逆向计算分析薄膜材料的热膨胀系数及杨氏模量.实验验证表明: 所制备的膜层附着力在1300~3400nm波段平均透过率为96.8%;在相同工艺条件下, 采用连接层所制备的薄膜附着力更好, 可以解决脱膜问题, 满足相应的附着力检测要求.
Abstract
The ultra-broad band anti-reflection film of 1300~3400nm waveband was designed and fabricated on TeO2 acousto-optic crystal. Starting the theory of thermal stress of thin film with the properties of TeO2,the stress diagrammatic sketch of thin film was established.Combing the properties of TeO2 crystal with torque determination method, the thermal expansion coefficient and Young’s modulus of the thin film materials were analyzed by analytical method of reverse calculation.The experiments show that the adhesion is better prepared under the same process conditions by using connecting layer. The film is protected from the problem of stripping and meets the corresponding requirements of adhesion test.
