Abstract
Quantum-efficient silicon photodetectors of VSL (The Netherlands) and SP (Sweden), were compared with the cryogenic absolute radiometer of VTT (Finland). Agreement between the detectors was found at a level of 10-4 when the data of four silicon detectors are combined. The comparison was performed at a laser frequency of 5,515 81 × 1014 Hz (λ = 543,515 nm in vacuum).
