  • 描述

硅(Si)通过 Czochralski(CZ)提拉生长,由于包含一些氧化物,导致9微米波段有吸收。 为了避免这种情况,可以通过Float-Zone(FZ)提拉生长材料。 光学硅一般是少量掺杂(5至40欧姆厘米)以获得10微米以上的最佳透射率,通常掺杂是硼(P型)和磷(N型)。 掺杂之后,硅具有另一个通带:30至100微米,其仅在非常高电阻率未补偿材料中有效。

CZ硅通常用作1.5-8微米区域的红外反射器和窗口的基板材料。 由于9微米的强吸收带使其不适用于CO2激光传输应用,但由于其高导热性和低密度,它经常用于激光反射镜。

硅材质主要用于加工硅窗口片,硅透镜,应用波段为1.5-7um。硅反射镜用于CO2激光器和光谱仪。

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.
