The operation of the imaging spectrometer based on the axicon is modelled in the Matlab. The imaging spectrometer consists of an annular scanning slit, lenses and axicon. Simulation conducted for two schemes: non-imaging and imaging. We simulated and showed that it is possible to obtain a spectral resolution of 10 nm and a point spread function of 30-50 μm. We obtained the spectral distribution from a model object with parts in which the wavelength of monochromatic radiation took one of three values: 0.46 μm (blue), 0.54 μm (green), 0.70 μm (red).
