OL 345 Radiometric and Photometric Calibration Standard

Product Description:

The OL 345 is a rugged, versatile radiometric and photometric standard capable of accurately calibrating a large variety of light measuring instrumentation. It is comprised of a 45-Watt tungsten-halogen lamp and a removable flashed opal diffuser mounted in an air-cooled cylindrical housing. The ability to insert a narrow bandpass interference filter in the beam enables radiometers and various detectors to be calibrated for absolute spectral response at each filter wavelength.
