  • 分光五角棱镜
    镀氟化钙的分光五角棱镜

    分光五角棱镜是通过在棱镜其中一个倾斜面上添加一个楔,并加上部分反射涂层,可以将五角棱镜用作分光镜,透过率/反射率(T/R)比为50/50,其他比例的分光五角棱镜也能根据您的要求定制。

  • 装配的长波通滤镜
    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。

    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.   Crystallographic properties Syngony Cubic Crystal Form Poly or Single Crystal Lattice Constant 5.66 Cleavability <111>, non-perfect Molecular Weight 72.6 Physical properties Density, at 20 °C 5.33 Hardness, Mohs 6.3 Dielectric Constant for 9.37 × 109 Hz at 300 K 16.6 Melting 937 Thermal Conductivity, W/m·K at at 293 K 59 Thermal Expansion, 1/K at 298 K 6.1 × 10-6 Specific Heat Capacity, J/(kgK) at 273-373 K 0.074 Bandgap, eV 0.67 Knoop Hardness, kg/mm2 800 Youngs Modulus, Gpa 102.66 Shear Modulus, GPa 67.04 Bulk Modulus, GPa 77.86 Debye Temperature, K 370 Poissons Ratio 0.278 Elastic Coefficient C11=129, C12=48.3, C44=67.1 Apparent Elastic Limit 89.6 MPa (13000psi) Chemical properties Solubility in water None Solubility in acids Soluble Molecular Weight 72.59 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.   Crystallographic properties Syngony Cubic Lattice Constant, A 5.43 Physical properties Density 2.33g/cm3 Hardness, Mohs 7 Dielectric Constant for 9.37 x 109 Hz 13 Melting point, оС 1414 Thermal Conductivity, W/m·K at 313 K 163 Thermal Expansion, 1/K at 293 K 2.6x10-6 Specific Heat Capacity, J/(kg°C) 712.8 Bandgap, eV 1.1 Knoop Hardness, kg/mm2 1100 Youngs Modulus, Gpa 130.91 Shear Modulus, GPan 79.92 Bulk Modulus, GPa 101.97 Debye Temperature, K 640 Poissons Ratio 0.28 Chemical properties Solubility in water None Molecular Weight 28.09 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. This material is particularly well suited for high-performance common aperture systems that must perform across a broad wavelength spectrum. Specifications: Material: ZnS MultiSpectral Diameter Tolerance: --------------------- +0.0, -0.1mm Thickness Tolerance: -------------------- ±0.1mm Clear Aperture: ---------------------------->85% Parallelism: -----------------------------------3 arc minute Surface Quality: ----------------------------80-50 scratch and dig Wavefront Distortion: -------------------- λ /2 per 25mm @633mm Bevel: -----------------------------------------Protective  (<0.2mm x 45° ) Coating: -------------------------------------- Optional (Uncoated, AR Coating, etc.) 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.
