Combination Photometer/ Spectroradiometer with NVIS test capability

Brightness measurements as well as Chromaticity and NVIS measurements are made using this equipment. The target is viewed through an eye piece and the unit measures only what is covered by the dark dot. This dot is actually an aperture which the user selects prior to measuring. This unit is periodically calibrated so all measurements are NIST traceable.

Photometer Service & Calibration

A NIST traceable Intensity secondary Standard lamp set at 2856 deg. Kelvin is used as the basis for all Luminance and Illuminance calibrations. All equipment used in the calibration procedures are frequently calibrated and abide to a traceability chart which track every piece of NIST traceable equipment in the laboratory.
