Abstract
This paper gives the results of experimental studies of the spread function and practical resolving power of a digital spectrograph based on an MFS-8 spectral device and an MAES linear photodiode array. It is established that, as the width of the spectrograph’s exit slit increases from 3 to 100 μm, the spread function remains bell-shaped, with the maximum in the middle. The recorded spectral lines become narrower than the entrance slit as it increases above 15–30 μm. The experimental values of the practical resolving power monotonically increase as the slit width decreases from 90 to 10 μm, and then remain constant for 6 and 3 μm.
