Abstract

A compact IR spectrograph based on a line array of pyroelectric sensors and operating in the vicinity of 10-μm-wavelength has been developed. The development was motivated by various tasks requiring prompt measurement of the spectral characteristics of multifrequency radiation in this spectral range. The spectrometer’s performance was tested using a wavelength-tunable CO2-laser. With a fixed position of the diffraction grating, the spectrometer covers a wavelength range of approximately 0.6 µm (wavenumber range of approximately 50 cm–1) with a spectral resolution of approximately 0.02 µm (which is approximately 0.2 cm–1), which allows one to reliably separate two adjacent CO2-laser lines.
