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。
色散棱镜用于需要将入射光分离成其组成波长的应用中。例如，当白光进入色散棱镜时，它被分成三个部分:红、绿和蓝。色散棱镜是理想的光谱学或激光调谐。

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。
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。
N-BK7五角棱镜
在光学系统中，五棱镜是用来定义直角的，它能够提供右手图像，特点是使光线偏离90°。五角棱镜是具有五个面的棱镜，不受轻微运动的影响。福州优恩立光电提供多种五角棱镜，在紫外，可见光，和红外光谱范围具有良好的光学性能。
镀氟化钙的分光五角棱镜
分光五角棱镜是通过在棱镜其中一个倾斜面上添加一个楔，并加上部分反射涂层，可以将五角棱镜用作分光镜，透过率/反射率(T/R)比为50/50，其他比例的分光五角棱镜也能根据您的要求定制。
N-BK7和融石英楔角棱镜
楔角棱镜是一种具有平面倾斜面的光学元件，通常各面以很小的角度相互倾斜，它能将光线转向较厚的部分，通常可以用作隔离元件。楔角棱镜也可以用来产生一个小偏差，不允许光线返回来源。
BK7和熔融石英玻璃道威棱镜
道威棱镜由H.W.多芬发明，多芬棱镜也被称为反转棱镜。当棱镜绕其长轴旋转时，通过棱镜所看到的图像的旋转速度是棱镜旋转速度的两倍。道威棱镜比较特殊，有时用于特殊的应用。入口和出口表面都有防反射涂层
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.
