Pro-Lite supplies certified lamp standards from Labsphere and Optronic Laboratories that provide known luminous flux, spectral radiant flux or spectral irradiance that are used to calibrate integrating sphere systems, as well as photometers and spectroradiometers. We also offer standards of forward spectral flux which are used to calibrate integrating sphere photometers for the measurement of 2π flux.
All standards are incandescent lamps that are calibrated using NIST-traceable standards. The Labsphere spectral flux standards are in addition calibrated under the guidelines recommended by NVLAP accreditation (ISO 17025) for the highest degree of confidence.
