这些分光镜以最小的敏感度分散能量，入射光束和反射光束的偏振态基本相同。宽带消偏振分光棱镜混合镀膜具有一定吸收能力，但偏振灵敏度最低。由于混合镀膜层的金属性质，这些立体分光镜不适用于高功率激光器。

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。
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.

3、ZnS material:
ZnS MultiSpectral Under intense heat and pressure, defects within the crystalline lattice are virtually eliminated, leaving a water-clear material with minimal scatter and high transmission characteristics from 0.4 to 12 microns.

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.
棒透镜
用于光纤耦合和激光二极管光束成形，工作距离为0mm的透镜非常适用于单模和多模光纤和激光二极管的准直，因为透镜可以直接定位并直接粘合在发射源上。 对于聚焦应用，或者镜头不能与发射源直接接触的情况下，所有镜头也可以具有小的工作距离。UNI Optics可提供Φ1~Φ15mm的尺寸，数量和尺寸，包括抛光/磨削表面的差异，可根据客户要求提供。
