This Technical Report outlines procedures for determining the spectral responsivity function of photodetectors.
The report is divided into two parts:
1. The determination of the relative spectral responsivity function.
Various methods are presented and instrumental details are discussed. Sources of errors are listed together with diagnostic tests and proposals for remedial action.
2. The absolute calibration.
Three different methods are presented for transforming the relative spectral data into absolute values.
This report is intended to serve as a guide for anyone wishing to assemble, test or modify new or existing instruments. Its purpose is to stimulate critical judgement of various options in every phase of the development of such instrumentation rather than to present a single solution.
The publication is written in English, with a short summary in French and German. It consists of 77 pages with 10 figures and is readily available at the National Committees of the CIE or via the CIE Webshop.
The report was prepared by the following members of CIE Technical Committee 2.2 "Detectors".
