镀增透膜蓝宝石窗片

蓝宝石窗片在高温下保持高强度,具有良好的热性能和卓越的透明度。它在高达1000°C的温度下对常见的酸和碱具有耐化学性,对于低于300°C的氟化氢也具有耐化学性。 这些特性促使其广泛用于需要在从真空紫外线到近红外范围内的进行光传输的恶劣环境中。

  • 描述

蓝宝石窗片由单晶蓝宝石制成,因其极高的表面硬度、高导热性、高介电常数以及对常见化学酸和碱的耐受性,使其成为要求苛刻的应用领域(如激光系统)的理想选择。蓝宝石是仅次于钻石的第二个最坚硬的水晶,由于其结构强度,蓝宝石窗片可以比其他普通介电窗片更薄,以提高透明度。在化学上,蓝宝石是单晶氧化铝(Al2O3),可用于0.2-5.5μm的透射率范围。

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.
