偏振分光棱镜

偏振分光棱镜由两个直角棱镜胶合而成，其中一个棱镜的斜面镀有偏振介质膜。当与正常入射、非偏振光一起使用时，入射光被分成两束偏振光，P偏振光可直接穿过，S偏振光以90°角反射出来。

描述

1. 什么是偏振分光棱镜？

偏光分光棱镜由两个直角棱镜粘合在一起构成。一棱镜的斜面镀有一层特殊的多层介质膜。当圆偏振光或自然光垂直进入立方体时，它被分成两条线偏振光。透过的光束为P偏振光，反射光束为S偏振光。当线偏振光进入时，它同样分成两束。但是，两个输出光束的能量比取决于入射光束的偏振。偏振分光棱镜可用于许多激光波长和宽带范围。

2. 偏振分光棱镜如何工作？

偏光分光棱镜的设计目的是在特定的反射率/透射率比下（r/t），以不确定的偏振趋势分离未极化的光。偏振光分光棱镜设计用于将光分为反射的S偏振光和透射的P偏振光。

3. 偏振分光棱镜有哪些用途？

分光棱镜也是一种滤光片，用于激光束的分离和组合。但偏振分光棱镜是用来分散或组合两个垂直偏振激光束。偏振分光棱镜的性能取决于其具体镀膜规格。它们是激光或照明系统中的常见部件。也适用于荧光应用、光学干涉测量、生命科学或半导体仪器。光可以按总强度、波长或偏振状态的百分比进行分散。选择合适的分光棱镜，需考虑类型、镀膜、透过率范围和损伤阈值。

红外材料

1. Germanium (Ge)

Germanium (Ge) is the preferred lens and window material for high performance infrared imaging systems in the 8–12 μm wavelength band. Its high refractive index makes Ge ideal for low power imaging systems because of minimum surface curvature. Chromatic aberration is small, often eliminating the need for correction.

2. Silicon (Si)

Silicon (Si) is grown by Czochralski pulling techniques (CZ) and contains some oxygen that causes an absorption band at 9 microns.To avoid this, material can be prepared by a Float-Zone (FZ) process. Optical silicon is generally lightly doped (5 to 40 ohm cm) for best transmission above 10 microns, and doping is usually boron (P-type) and phosphorus (N-type). After doping silicon has a further pass band: 30 to 100 microns which is effective only in very high resistivity uncompensated material.

CZ Silicon is commonly used as substrate material for infrared reflectors and windows in the 1.5-8 micron region. The strong absorption band at 9 microns makes it unsuitable for CO2 laser transmission applications, but it is frequently used for laser mirrors because of its high thermal conductivity and low density. Application as window, lens in the 1.5 - 8 um region; Mirror for CO2 laser and spectrometer applications.

4. ZnSe material

ZnSe is a preferred material for lenses, windows, output couplers and beam expanders for its low absorptivity at infrared wavelengths and its visible transmission. For high-power applications, it’s critical that the material bulk absorption and internal defect structure be carefully controlled, that minimum-damage polishing technology be employed, and the highest quality optical thin-film coatings are used. The material absorption is verified by CO2 laser vacuum calorimetry. Our quality assurance department provides testing and specific optics certification on request.

ZnSe is non-hygroscopic and chemically stable, unless treated with strong acids. It’s safe to use in most industrial field, and laboratory environments.
