The reduction of near infrared output from the tungsten-halogen lamp reduces the effects of stray light within the monochromator portion of a spectroradiometer. The RS-12DN has a three-inch exit diameter with uniformity ±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).
