About This Product

■Summary

RS-12D is the absolute standard illuminant for NIST traceable spectral radiance and brightness. The aperture diameter is 3inch (65mm) and the uniformity is ±3%. It is also possible to perform ISO17025 calibration at maximum brightness and calibration at user-specified brightness. We issue a calibration certificate based on proper calibration. The RS-12D series is a standard light source for calibration that complies with U.S. NIST standards. Used for calibration of spectral radiance and brightness. Gamma Scientific is an ISO17025 calibration laboratory certified by NVLAP, so we can calibrate not only the maximum brightness value, but also the specific brightness value and filter/aperture that the user desires. In addition to RS-12D, RS-12DN is also available as a light source for calibrating spectral radiance meters and radiance meters used for measuring cockpit displays (NVIS displays) with near-infrared output based on military standards.
