薄膜光学是物理学的年青分支,它主要研究光在分层介质中的传播规律。其最早萌芽于十七世纪中叶。真正的发展是从1930年出现了油扩散泵使商用镀膜机得以间世以后,从此,各种减反膜、金属膜反射镜与滤光片相继镀制成功。实际的需要促进了理论的发展,四十年代中期,各国学者先后提出 Thin film optics is a young branch of physics, it mainly studies the law of light propagation in layered media. Its earliest germination in the mid-seventeenth century. The real development is from 1930 oil diffusion pump commercial coating machine to be able to come after world time, since then, all kinds of antireflective film, metal film mirror and filter successively plating success. The actual needs promoted the development of the theory. In the mid-1940s, scholars of various countries proposed one after another
