A design and parameters of the IR spectrograph based on an MS2004I monochromator-spectrograph and a hybrid microcircuit of a one-dimensional 1 × 384 InAs focal plane array for registration of fast processes (the registration time from 0.2 ms) are presented. The obtained spectral resolution is 0.3 nm/element at a wavelength of 1.7 μm. The wavelength range registered in a fixed position of the diffraction grating at this wavelength is 118 nm.
