The RS-12D Series consists of NIST Traceable sources that can be used as white light standards of spectral radiance or luminance.
The base unit is supplied as a calibrated source, with calibration options including ISO 17025 calibration at maximum luminance, calibration at a user-specified Footlambert value, or via insertion of an optional filter/aperture assembly, can be incorporated into an NVIS display measurement system (please refer to model RS-12DN NVIS).
Full calibration, along with the appropriate calibration certificate is supplied with designated units, based on the requested option.
