FIELD: physics.
SUBSTANCE: spectrometer includes an input lens, a slit, a collimating lens, a spectroscope, a projection lens, a photodetector array, a small digital block and a digital video monitor. The spectrometer is made in the form of a two-mirror matrix anastigmat constructed on two orthogonally crossed quarter-cylindrical reflectors intended for forming a matrix of images with discrete pancratic.
EFFECT: providing the possibility of simultaneous structuring of wide and narrow zones of light flux in a wide spectral range.
