A prototype of the hyperspectrometer based on the Offner scheme has been tested. Drawings have been produced and the main mirror elements of the hyperspectrometer including diffraction grating on a convex spherical surface have been fabricated. The profile of the grating groove has been measured and light energy distribution in diffraction orders has been modeled as a function of wavelength. Optomechanical elements for the necessary alignments of the hyperspectrometer elements have been designed and manufactured. Adjustment of the optical prototyping scheme has been implemented and point images for three wavelengths of monochromatic radiation have been obtained. Distribution of light energy in diffraction orders and maxima positions are in an agreement with the simulation results. The spectrometer has also been tested on test images in polychromatic radiation under the control of the developed software.
