ActiveTest method of temperature coefficient of infrared refractive index for infrared optical glass —Normal incidence method
红外光学玻璃红外折射率温度系数测试方法 垂直入射法
Application Summary AI generated
This standard specifies the normal incidence method for measuring the temperature coefficient of the infrared refractive index of infrared optical glass. It is applied in the optical materials industry, specifically for quality control and performance evaluation of glass used in infrared optical systems, such as thermal imaging lenses and military targeting devices. The test method ensures accurate characterization of how the glass's refractive index changes with temperature, which is critical for maintaining optical performance in varying thermal environments.
