Abstract
Various kinds of photo-detectors based on different materials have been successfully developed to expand the horizon of human eye. Spectral responsivity is the most important technical parameter for photo-detectors, which can mirror the converting ability of optical signal to electric current. Its measurement accuracy is critical for the development and research of photo-detecting field. In this paper, we will introduce the facility for photo-detector’s spectral responsivity calibration in the wavelength range of 300 nm to 1000 nm, built in National Institute of Metrology (NIM), China. Measurement uncertainty is analyzed at the wavelength 500 nm as an example. By adopting comparison method, choosing reference detectors with known standard value and traceable to SI units through upper level standards, we demonstrated a reliable measurement procedure for absolute spectral responsivity of photo-detectors.
