Abstract

An equipment for measuring transmission index of optic material in high temperature is introduced in the paper. A kyptol was used as infrared light source and narrow band filter was used to generate the monochrome light. Two parallel flat reflectors separated the light source into two ways, one was sample beam and the other was reference beam. A chopper was used to modulate the light and a lock-in amplifier was used to detect the infrared light. High precision temperature heater was used to control the temperature of sample material. The equipment has the ability to measure the transmission index of optic material from 1μm to 14μm and the temperature scope from room temperature to 700℃. Measurement principle and makeup of the equipment are introduced in the paper. Transmissions of Al₂O₃ and germanium in high temperature were reported in the end.
