Once is enough in radiometric calibrations

“…Subjective measurements based upon visual inspection were replaced by objective measurements performed by electro-optical sensors. NIST eliminated such visual comparisons in their photometric and radiometric measurements and implemented additional step to improve radiometric and photometric calibrations [ 20 ], including the modernization and automation of the laboratory facilities and the establishment of an ISO Guide 25 compliant quality system [ 21 , 22 ]. The quality system has since been updated to comply with the new NIST-wide standards based upon the newer ISO Guide 17025 [ 23 ].…”
