Paper Abstract

The NPL maintains and disseminates a spectral responsivity scale from the VUV to the infrared and has many years' experience of the calibration of optical radiation detectors. The measurement of spectral responsivity of a detector in any part of the spectrum is best divided into two processes: - measuring the relative spectral responsivity over the wavelength region of interest - measuring the absolute responsivity at one wavelength. This makes possible the use of different transfer standards and techniques for the different scales and minimises the uncertainties.
