摘要
红外光学薄膜材料在红外光学系统中的应用非常广泛,其折射率是光学薄膜设计的重要参量,鉴于空间应用的特殊需求,红外光学薄膜通常工作在低温条件下,红外光学薄膜材料的折射率会随温度改变而发生变化,对于红外光学薄膜的研制有很大影响。论文研究了红外光学薄膜材料折射率的温度特性,总结了红外光学薄膜材料折射率色散模型,并对红外光学薄膜材料折射率温度特性研究发展趋势进行了展望。
Infrared optical film is widely used in Infrared optical systems. Its refractive index is an important parameter of the optical film design. Because of the special requirements of space application,infrared optical film is usually used in low temperature. The refractive index of infrared optical film material is always changed with the temperature,and this char-acteristic have a great effect on the manufacture of the infrared optical film. In this paper,the temperature characteristic of infrared optical film was discussed,and the basic theory of the refractive index dispersion was summarized. And we discussed the tendency of the development of the temperature characteristic.
