Abstract

The responsivity of two optical detectors was determined by the method of direct substitution in four different NIST measurement facilities. The measurements were intended to demonstrate the determination of absolute responsivity as provided by NIST calibration services at laser and optical-communication wavelengths; nominally 633 nm, 850 nm, 1060 nm, 1310 nm, and 1550 nm. The optical detectors have been designated as checks standards for the purpose of routine intracomparison of our calibration services and to meet requirements of the quality-system document, ISO 17025. The check standards are two optical-trap detectors: one based on silicon and the other on indium gallium arsenide photodiodes. The four measurement services are based on: (1) the Laser optimized cryogenic radiometer (LOCR) and free field collimated laser light; (2) the C-series isoperibol calorimeter and free field collimated laser light (3) the electrically calibrated pyroelectric radiometer and fiber coupled laser light; (4) the pyroelectric wedge trap detector, which measures light from a lamp source and monochromator. The results indicate that the responsivity of the check standards, as determined independently using the four services, agree to within the published uncertainty ranging from approximately 0.02 % to 1.24 %.
