2，金属镀膜反射镜具有什么特点？
金属涂层镜具有以下特征：
光谱范围广
对入射角和偏振态不敏感
低成本
非耐用品
反射率相对较低
激光损伤阈值低
3，优恩立光电能为您提供什么金属镀膜反射镜？
常用规格：
基底材料：N-BK7，熔融石英，耐热玻璃，浮法玻璃
尺寸公差：+/- 0.1mm
表面质量：60-40
平行度：3'
平整度：λ/ 4 / 25mm @ 633nm
倒角：保护性
一个表面：抛光和金属镀膜
另一个表面：细磨
注：铝是最广泛使用的金属反射膜，从近紫外到近红外，具有高反射率，且成本低。银在可见光和近红外波长下的反射率高于铝膜，但空气中的银会快速氧化，颜色变暗，使薄膜性能和硬度迅速下降。金膜具有良好的一致性，在近、中、远红外范围内具有高反射率，可以有效控制热辐射，但它比较柔软，容易擦伤，应该非常注意清洁，而且成本很高。
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。
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。
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。
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.
