ABSTRACT:
A calibration instrument for calibrating a temperature probe, such as pyrometer, uses a stable light source and a filter to simulate a blackbody of a known temperature. An alignment tool aligns a light-emitting surface of the calibration instrument to the input of the temperature probe. The calibration instrument may include a fiber optic bundle to transmit light from the light source to the light emitting surface.
