COMPACT MULTICHANNEL OPTICAL SPECTROMETERS

This paper discusses the results of developing high-aperture multichan nel optical spectrometers based on unconventional concave ruled gratin gs and linear CCD photodetectors. It is shown that one can use these s pectrometers, in particular, when optimizing the operation of a spectr um-exciting source based on an inductively coupled plasma (ICP) in rea l time and when studying the excitation kinetics of the spectra of a m ultielement specimen with pulsed input of dry residues into an ICP.
