CVD-ZnSe硒化锌窗片红外透镜分束镜
CVD-ZnSe硒化锌窗片红外透镜ZnSe可用作生产IR红外范围的光学元件(窗片、透镜、棱镜)材料,包括无源激光光学元件。CVD-ZnSe的结构非常均匀,它具有卓越的光学透射性能,散射和吸收损失极低。CVD - ZnSe是高功率激光窗口片和多光谱应用的选择,有效透射范围为0.5 - 19 um。它具有出色的成像特性,高抗热冲击性,几乎在所有操作环境中都很稳定。这种材料柔软且不吸湿。CVD-ZnSe硒化锌窗片红外透镜硒化锌棱镜ZnSe的物理性质 光学特性热光系数,(dn / dT)6.1 x 10 -5@ 10.6um @ 298-358 K,1 / K.Restrahlen peak, mm45.7反射损耗@ 10.6um(2个表面),%29.1反射不均匀性(dn/n)@ 0.633um,小于3 x 10 -5ZnSe折射率与波长的关系λ,μm?λ,μm?λ,μm?0.542.67543.002.437610.602.40280.582.63123.40 2.435611.402.39740.622.59943.802.433911.802.39450.662.5755 4.202.432412.202.39150.702.55684.602.430912.602.38830.74 2.54185.002.429513.002.38500.782.52955.402.428113.402.3816 0.822.51935.802.426613.802.37810.862.51076.202.425114.202.37440.902.50346.602.423514.602.37050.942.49717.002.421815.002.36650.982.49167.402.420115.402.36231.002.48927.802.418315.802.35791.402.46098.202.416316.202.35341.502.45608.602.414316.602.34871.802.44969.002.412217.002.34382.002.44609.402.410017.402.33872.202.44379.802.407717.802.33332.602.440110.202.405318.202.3278 根据应用,我们使用两种等级的CVD - 具有不同光学性质的ZnSe。8um以上无差异(见图1)。 图1 CVD-ZnSe窗口厚度为10 mm的透射光谱。G 1G 2吸收指数(5-8)x10-41x10-3@ 10.6 um,小于1/cm损伤阈值,不小于,kW / cm 22-3-欢迎来电咨询定制:CVD - ZnSe坯料的直径为2-200 mm,厚度为15-20 mm。类型长宽/直径 mm厚度, mm表面质量, scr/digPN 平面7140/20 , 60/40W-ZNSE-DX-TX平面,带孔7140/20 , 60/40WWDR-ZNSE-DX-TX契形 7140/20 , 60/40W-ZNSE-DX-TX-C契形,带孔7140/20 , 60/40WWDR-ZNSE-LX-HX-TX契形,带孔/凹槽7 140/20 , 60/40WWDR-ZNSE-DX-TX5ZnSe窗片型号:类型直径 mm厚度, mm表面质量, scr/digPNplano-plano25.4360/40W-ZNSE-D25.4-T3plano-plano38.1360/40W-ZNSE-D38.1-T3plano-plano50.8360/40W-ZNSE-D50.8-T3plano-plano76360/40W-ZNSE-D76-T3plano-plano100860/40W-ZNSE-D100-T8plano-plano101.68.360/40W-ZNSE-D101.6-T8.5ZnSe分束镜型号类型直径 mm厚度, mm表面质量, scr/digPNplano-plano25.4160/40BS-ZNSE-D25.4-T1-Cplano-plano38.1160/40BS-ZNSE-D38.1-T1-Cplano-plano50.8360/40BS-ZNSE-D50.8-T3-Cplano-plano76360/40BS-ZNSE-D76-T3-Cplano-plano100860/40BS-ZNSE-D100-T8-Cplano-plano101.6860/40BS-ZNSE-D101.6-T8-C
