光学膜保温性能的研究

研究了光学干涉膜对光的选择性，分析了其厚度对最大反射峰的影响。采用自制的隔热效果测试装置对干涉膜的隔热效果进行了测定。研究表明干涉膜反射光的波长范围主要由其厚度决定，随着光学厚度的增加，主要反射光波波长位置逐渐从较短区域向较长区域迁移；在红外灯照射下干涉膜和空白玻璃之间的温差最高可达2.4℃。

Study on Heat Preservation of Optical Film

This research is about the thickness and optical thickness for the main wavelength of reflected light district location and transmission， to the two-component multi-layer composite film. Research shows that: two-component multi-layer films mainly reflected wavelength range is mainly determined by the optical thickness， little to do with the whole thickness; Along with the increase in optical thickness， mainly reflecting light wavelength is moving from the shorter position gradually to the region longer regional migration; the thickness of the multi-layer film whose reflective peak is in Near-infrared is about 35μm～70 μm. Through studies， the optical thickness with the main reflective wavelength relations has basically be found.
