Ultimate White Light Standard for Calibrating Spectroradiometers, Radiometers, and Photometers; The RS-12D Series from Gamma Scientific

April 15, 2020

The Gamma Scientific RS-12D Series consists of NIST Traceable sources that can be used as white light standards or spectral radiance or luminance. The base unit is a calibrated source with calibration options including ISO 17025 calibration at maximum luminance, calibration at a user-specific footlambert value, or via insertion of an optional filter/aperture assembly which can be incorporated into an NVIS display measurement system (RS-12DN).

The RS-12D is ideal as a calibration source for spectroradiometers, radiometers, and photometers, or it can be used to calibrate detector responsivity, or measure reflectance and transmittance. It features a correlated color temperature of 2856K ± 25K with a 3-inch diffuse exit diameter with ±3% uniformity. The calibrated wavelength ranges are between 380-1100 nm at 5 nm intervals.
