- Standard of spectral radiance and luminance
- RS-12B white-light standard without NVIS requirements

- ANVIS output with 10-10 AR
- NIST Traceable
The RS-12 is a versatile NIST-traceable calibration light source. Use it as a white-light standard of spectral radiance or luminance. Or, employ its filter/aperture assembly for an NVIS display simulation source approximating a green cockpit display with optimal near-infrared output against which a spectroradiometer or radiometer can be calibrated.
Lower near-infrared output from the tungsten-halogen lamp reduces the effects of stray light within the monochromator portion of a spectroradiometer. The RS-12 has a three-inch exit diameter with uniformity of ±3%.
Three calibrations and certificates are supplied. First, a white-light source calibration is performed from 380 to 1100 nm. Nominal luminance output is 700 footlamberts and correlated color temperature is set at 2856 K ± 25 K. The second calibration is with the filter inserted with nominal luminance output of 45 footlamberts. The third calibration is with the filter and aperture. Nominal output is 1 footlambert and 10-10 AR (Anvis Radiance).
