| 摘 要： | 建立了高温光谱透射率测量装置,测量了石英光学窗口在300～1100K温度范围内的可见光及近红外四个光谱下的法向透射率。根据样件的光谱透射率测量数据,基于双厚度法计算获得了石英光学窗口的光谱折射率和光谱吸收系数。利用光谱折射率和光谱吸收系数预测的另一种厚度的样片透射率数据与实验测量值的相对误差小于10%。

| Abstract: | An experimental device for measuring spectral transmittance at high-temperature was developed.By measuring,four bands of normal transmittance in visible and near infrared spectra were obtained for the optical quartz specimen at the temperature range of 300K to HOOK.The double-thickness method was used to analyze the experimental data to deduce the spectral refractive index and spectral absorption coefficient of the quartz.By the two spectral property parameters obtained previously,the spectral transmittance was theoretically forecasted for another sample. The comparison with the experimental data shows that the errors of predicted values are less than 10%. |
