Abstract:
A dispersive element in the form of the diffraction grating on a convex mirror surface is investigated. The groove profile of the grating is measured and the intensity distribution between the diffraction orders is calculated as a function of wavelength for the visible spectrum. Optomechanical elements for the required alignments of the spectrometer elements are designed and fabricated. Adjustment of a prototype optical scheme is implemented and point images for three monochromatic incident wavelengths are obtained. The energy distribution between the diffraction orders and the intensity maxima positions are in agreement with the simulation results.

Keywords:
spectrometer, groove profile, energy distribution between the diffraction orders, adjustment of a prototype optical scheme.
