什么是激光棱镜？
激光棱镜用于在许多光束控制或光束操纵应用中重定向激光束。 激光棱镜使用各种基板，涂层或两者的组合来实现特定波长范围的高反射率。 激光棱镜设计用于在多个表面内部反射激光束，以便重定向光束路径。 激光棱镜有几种类型，包括为不同类型的光束偏差设计的变形，直角或后向反射器。

激光等级透镜
激光透镜用于在各种激光应用中聚焦来自激光束的准直光。激光透镜包括一系列透镜类型，包括平凸透镜，激光划线透镜或激光发生器透镜。 激光头设计用于根据透镜类型以几种不同的方式聚焦光线，例如聚焦到一个点，一条线或一个环。许多不同的镜头类型可用于各种波长。

N-BK7角锥棱镜
角锥棱镜又称反射镜，它有三个相互垂直的表面和一个斜边面。通过斜边进入的光依次被三个表面反射，并通过平行于入射光束的斜边面出现，而不考虑入射光束的方向。由于其特殊的性能，常被用于距离测量、光学信号处理和激光等领域。
镀宽带增透膜的斜边直角棱镜
直角棱镜通常用于改变光路，或用于将光束重新定向90°。直角棱镜是设计成90°角的棱镜，根据棱镜的方向产生倒置或反转的左手图像，同时使用两个直角棱镜是理想的使图像或光束位移的应用。这些棱镜也被称为镜像反射棱镜。
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.
