Product Description General Introduction:Zinc selenide (ZnSe) is an optically inert material with high purity, strong environmental adaptability and easy processing. It has low transmission loss and good light transmission performance. Zinc selenide material has high transmittance in 600nm-16μm band, low absorption and thermal shock resistance, so it is the preferred material for high power CO2 laser optical components.Due to its good refractive index uniformity and consistency, the infrared material is also an ideal material for protecting Windows and optical components in current infrared (FLIR) thermal imaging systems. At the same time, zinc selenide materials are also widely used in medical and industrial thermal radiation meter and infrared spectrometer window and lens.Main Characteristics:1).The chemical properties of CVD ZnSe Of Germany IR and NIR matrials are inert;2). It has non hygroscopicity and high purity;3). Very compact and easy to machine;4). It has good absorption and scattering ability;5).The volume loss of this material is very low,6).It has high tolerance to thermal shock;7).It can maintain its stability under almost all environmental conditions.8).Round blanks and sheets are available in stock to meet your urgent needsThermal Properties:ItemsValueCoefficient of Thermal Expansion[K-1] @273K 7.1 x 10-6[K-1] @373K 7.8 x 10-6[K-1] @473K 8.3 x 10-6[K-1] @273K 7.1 x 10-6[K-1] @373K 7.8 x 10-6[K-1] @473K 8.3 x 10-6Thermal conductivity[JK-1m-1s-1] @298K18Heat capacity[Jg-1K-1] @298K0.339Mechanical Properties:ItemsValueHardness:Knoop, 50g load [kg mm-2] 110Vickers, 1kg load [kg mm-2]110112Flexural strength(modulus of rupture)4pt. loading [psi] 4pt. loading [MPa] 8 x 10355Fracture toughness(critical stress intensityfactor, KIC values)[MPa m, Vickers, 100g]0.5Posssion's Ration u0.343Young's modulus[psi][GPa]9.75 x 10667.2Poisson's ratio0.28Crystal structureCubicGrain size50-70umDensity [g/cm-3] @298K5.27Resistivity [ cm]~1012Chemical purity [%]99.9996Optical Properties:ItemsValue10% transmissionlimits (t=6mm)0.5μm - 22μmIndex of refractioninhomogeneity (Dn/n)<3ppm @633nmThermo-optic coefficientdn/dT (298-358K)K-1 @ 0.6328μm K-1 @ 1.15μm K-1 @ 3.39μm K-1 @ 10.6μm 1.07 x 10-47.0 x 10-56.2 x 10-56.1 x 10-5 Bulk absorption coefficientcm-1 @ 1.3μm cm-1 @ 2.7μmcm-1 @ 3.8μmcm-1 @ 5.25μmcm-1 @ 10.6μm 5.0 x 10-37.0 x 10-44.0 x 10-44.0 x10-45.0 x 10-4Main Applying Fields:1).High energy CO2 laser system2).High resolution forward looking infrared (fur)3).Protection window of thermal imaging equipment4).Small size windows and lenses for medical and industrial applications, such as thermometers and spectrometers.5).
