Abstract :
Hollow sapphire waveguide have been successfully employed for remote radiometric temperature measurements over an extended temperature range (30 degrees C to 1650 degrees C). These waveguides not only exhibit an infrared transmission window from 10 to 17 mu m, which permits low temperature blackbody detection, but the sapphire also possesses an intrinsic melting point of 2053 degrees C, enabling their operation in high temperature environments.
