About this work
Pictured is a method for testing high temperature measurements by comparing the color spectrum of light at various power settings with an Optical Pyrometer. The devices are calibrated at NIST. The power through the bulb is varied and monitored by the meter on the table. The scanning device that the technician is looking though is adjusted till the color scheme viewed within in the device matches the color of the emanating from the bulb at the particular power setting.
