Spectral Sensitivity Calibration Setup for Spectro Analytical Instruments

An installation for calibrating the spectral sensitivity of a spectroanalytical instrument (SAP) is presented. The special feature of the installation is that a set of narrow-spectrum radiation fluxes enters the SAP. The developed optical scheme of the calibration radiation source included in the installation makes it possible to obtain a set of such radiation fluxes. The fluxes were measured by a reference photodetector precisely at the SAP inlet, which eliminated the need to take into account the influence of medium transmission on the measurement results.
