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。
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.

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。
可视光/近红外镀膜的双凹透镜
双凹透镜是一种带有两个凹面的负焦距的光学透镜，常用于光束扩展、图像缩小或光投影等应用，也是扩大光学系统焦距的理想选择。优恩立公司可为您提供广泛用途的，带有多种涂层的双凹透镜。
