Gamma Scientific manufactures a wide range of calibration light sources. The RS-10D is a precision source of radiant flux used to calibrate spectroradiometers and other light measurement instrumentation. The RS-12 is a versatile light source that can be used as a white light standard of spectral radiance or luminance, with optimal near-infrared output for spectroradiometer calibration.
