FIELD: physics.
SUBSTANCE: proposed spectrometre to generate reference radiation, wideband laser and optical system to focus and intercross light beams in measured volume. Radiation from measured volume is registered by monochromator with multichannel photo detector. Proposed spectrometre comprises extra monochromator with photo detector to simultaneously register wideband laser radiation.
EFFECT: higher accuracy thanks to allowance for spectrum shape fluctuation.
