Pellin-Broca prsim

Then the author calculated the transmissivity of representative polarization prism,just as Rochon prism s in the crystal optics.

利用一套较为简便的公式确定了各向异性的单轴晶体———方解石内非常光(e光)的传播方向,接着应用各向异性单轴晶体和各向同性介质间的“菲涅耳公式”计算了晶体光学中具有代表性的偏振棱镜———洛匈棱镜的光强透射率。

In this paper, structure, polarizing principle and characteristics of the Rochon prism used in HITACHI 180_Series Zeeman atomic absorption spectrophotometers are described.

简述了日立１８０系列塞曼原子吸收仪的洛匈棱镜的结构、起偏原理、偏振特性，以及常见故障。

This article given the accurate description of reverse splitting angle of the Rochan prism in detail,and compared to the forward splitting angle;it also analysed the reason why a branch of beams extinction ratio is very poor,The reason is that it occurs conoscopic interference when light transmission along the optic axis.

给出了洛匈棱镜反向应用时的分束角的精确表达式 ,并与正向应用时的分束角作了比较 ;分析了反向应用时其中一束光消光比不高的原因 :光束顺着光轴传播时产生的锥光干涉所致。
