The optical spectrometer simultaneous has two arrays comprising detectors a semiconductor or of the multipliers of photoelectron

摘要

The invention relates to an optical spectrometer simultaneously to two arrays of semiconductor detectors of lines or of the multipliers photoélectrons.pour increase the spectral range simultaneously available and to optimize the spectral resolution in an optical spectrometer simultaneous networks to rowland, two gratings concave of a dispersion (1, 2) having a radius of curvature of which are identical, are arranged in such a way that their focal circles are coïncidents.application in particular to the analytical spectrometry.
