中文摘要：
蓝宝石单晶表面图形化作为一种全新的减反增透手段而受到广泛关注，然而在服役过程中其透过率将会由于温度的改变而发生变化，影响使用性能。本文通过高温红外光谱测试系统测试了图形化蓝宝石在25℃，300℃，400℃，500℃，600℃时3～6μm波段范围内的透过率，分析了温度对图形化蓝宝石透过率性能的影响。分析表明，表面图形化使室温条件下蓝宝石透过率在一定波段范围内上升且伴随有明显的光谱红移效应；温度上升使图形化蓝宝石透过率下降且红移现象加剧，随着温度不断升高蓝宝石透过率有一定程度回升；高温条件下表面图形化对蓝宝石透过率的影响不是十分明显。
英文摘要：
As a kind of bran-new anti-reflection treatment, patterned surface of sapphire single crystal which had gained widely attention. However, the transmittance decreased with the temperature change in serve process. The transmittance of patterned sapphire in the 3-6 μm band at the temperature of 25 ℃, 300 ℃, 400 ℃, 500 ℃, 600 ℃ was tested through the high temperature infrared spectrometer, the temperature effect on transmittance property was discussed in this paper. The testing results indicate that the transmittance of sapphire increased with spectrum red shift effect because of surface pattern at room temperature; High temperature caused the transmittance of patterned sapphire decline and the spectrum red shift effect aggravated, meanwhile, the transmittance rose again with the temperature promoted further; there was no obvious surface pattern effect on transmittance at high temperature.
