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

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

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。
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.
