Abstract

A spectroradiometer system is described which is designed to make measurements of the spectral energy distribution of light sources over the 0.25–2.5-μ wavelength range. A review is presented of some of the major experimental problems encountered in radiometry, in conjunction with the approach employed here to meet these problems. A single beam optical arrangement is used, with the photodetector signal being integrated over successive wavelength intervals and recorded in digital form. A digital computer then performs all subsequent data processing, including plotting of the final spectra. A brief functional description of the computer programs is presented, and the accuracy and reproducibility of the system are discussed.
