机器视觉带通滤光片
长波通滤镜
长波通滤光片适用于各种应用，如气体监测，温度，传感，热成像和运动传感等。长波通滤光片可阻挡较短波长并传输较长波长。 阻挡可以来自反射，吸收或组合。 带通中的透射可以通过第二表面上的增透膜涂层来增强。
宽带增透膜消色差透镜
消色差透镜用来减小或消除色差。消色差透镜设计亦有助于减少球面像差。消色差透镜是一系列应用的理想选择，包括荧光显微镜、图像中继、检测或光谱学。消色差透镜通常是将两个元件胶合在一起或将两个元件安装在一个机械件中，它所产生的光斑尺寸比类似的单透镜要小。
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。
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.
