Conservative design and rigid quality standards make Gamma Scientific sources the ones by which others are judged. They may be used as standards of irradiance or radiance, traceable to the National Institute of Standards Technology (NIST).
Near-constant radiant flux output is achieved via exclusive use of tungsten-halogen lamps. Ultra-stable, constant-current supplies utilize precision shunt-current measurement and comparison circuits built into the source housing.
With RS-70-X accessories, the RS-10D light source provides an absolute reference for producing standard outputs in a complete range of luminance, illuminance, spectral-radiance and spectral-irradiance units. Additional special filters and attenuators enable generation of different color temperatures, spectral outputs and intensities. Calibrations in photometric and/or spectroradiometric units are supplied and are traceable to NIST.
