镀金反射镜是光学和激光应用中的一个重要元件,精确测量其反射率,对于准确设计各种光学器件、改进激光器的运转特性和提高光学膜层的涂镀质量都具有重要意义,但用常规方法进行测量是比较困难的。基于测量红外窗材料低吸收系数方法的同样原理,我们设计出一种利用光声光谱方法来测量镀金反射镜高反射率的方法,此法简单、灵敏、方便、精度
Gold-plated mirrors are an important component in optical and laser applications. Accurately measuring their reflectivity is of great importance for accurately designing various optics, improving the operating characteristics of the laser and improving the quality of the optical coating. However, Method to measure is more difficult. Based on the same principle of measuring the low absorption coefficient of the infrared window material, we have designed a method that uses photoacoustic spectroscopy to measure the high reflectivity of gold-plated mirrors. This method is simple, sensitive, convenient and accurate
