A Color Photometer designed to calibrate tungsten sources to a standard source has been produced. It is accurate to within a few mired values, though not enough testing was done to specify its limits. There is also a good probability that the color -photometer can be used to find the color temperature of most tungsten sources including many that are not close to the color temperature of the standard source .
