Abstract

Lightpipe radiation thermometers (LPRTs) are the sensor of choice for temperature measurements in Rapid Thermal Processing (RTP) applications. At the National Institute of Standards and Technology (NIST), we have developed protocols for calibrating and characterizing LPRTs for use in RTP and other applications. In this paper, the LPRTs and the sodium heat pipe blackbody (Na-HPBB) used in the calibration process at NIST will be introduced. The calibration and characterization methods (spatial response, spectral response, temporal response, and optical inspection) of the LPRTs will be described also. Finally, a discussion of the application of LPRTs in an environment outside of the calibration laboratory, along with a list of recommendations for proper use of LPRTs, will be presented.
