Abstract: The color temperature of the radiating body is measured by separately measuring photoelectrically two different wavelength ranges of a beam emanating from the body, while the intensity of the beam is adjusted by an attenuating device so that the two different wavelength ranges are affected substantially the same and one of the wavelength ranges is maintained at a predetermined intensity.
