ShaFES: Shamakhy Fibre Echelle Spectrograph
Abstract
The paper describes the high-resolution fiber-optic echelle sp ectrograph developed for the Cassegrain focus of the 2-m telescope at the Shamakhy Astrophysical Observatory. The schematic optical circuit and circuit of a suspended part of the spectrograph are presented. Spectrograph operates in two modes with spectral resolutions of 28000 and 56000,in λλ3700"8500 ÅÅ region of wave lengths. Results of testing of positional and photometric performances of the spectrograph are analyzed.
