prisms助记

with the greater availability of lithium fluoride prisms, the use of this spectral range will probably be considerably extended.

由于更多地使用氟化锂棱镜，这个光谱区域的应用可能会有更大的发展。

optics: windows, prisms, lenses, beam expanders, laser mirrors, beam splitters, polarizers, etalons, filters, telecommunication optics and optical mounts, etc.

光学元器件：光学滤光片、透镜、激光镜、波片、窗口材料、分束片、偏振片、扩束镜、标准具、镀膜元件和光具座，等；

The second chapter firstly presents the basic conception of the polarizing principles of the prisms, and introduces the Snell theorem and the total reflection formula. The reflectivity formula of the s vibration as well as the p vibration is given.

第二章首先介绍了棱镜起偏原理的基本概念，引入了斯涅耳定理及全反射公式，并给出了s振动和p振动的反射比公式；
