Abstract

The invention relates to a method for calibrating a spectroradiometer (1), comprising the following method steps: capture of light measurement data by the measurement of the radiation of at least one standard light source (4) using the spectroradiometer (1) that is to be calibrated; derivation of calibrated data from the light measurement data by the comparison of the captured light measurement data with known data of the standard light source (4); and calibration of the spectroradiometer (1) according to the calibration data. The aim of the invention is to provide a reliable and practical method for calibrating the spectroradiometer (1). In particular, the synchronism of spectroradiometers (1) situated in different locations (9, 10, 11) is to be produced simply and reliably. To achieve this aim, the validity, i.e. the usability, of the standard light source for the calibration is checked by a comparison of the light measurement data of the standard light source (4) with light measurement data of one or more additional standard light sources (4) of the same type, the validity of the standard light source (4) being established if the deviations of the light measurement data of the s…
