增透膜和增反膜

Transmission Increasing Film and Reflection Increasing Film

文章首先阐述了在目视光学仪器表面镀一层增透膜的原理 ,通过计算得出应选择透明介质的折射率和膜的厚度 .由单层膜推广到双层膜及多层膜 .其次阐述增反膜的原理 ,通过类比的方式推出多层增反膜时光反射的公式 。

It has first been expounded at the eye inspection optical instrument surface and plates one layer of principle that transmission increasing film,and reaches thickness that should select the refractive index of transparent medium film by way of counting.By single layer of film popularizing to the double-lagers of films and the multiple-layers of films.Next expounding the principle that reflection increasing film,the method by way of the analogy is introduced to multiple-layers reflection increasing film to increase the formula and has finally explained the application.
