The echelle spectrometer PFES is designed by the
SSLab and used at
the prime focus of the 6m telescope BTA .
This spectrometer equipped with a CCD 1040x1160 pixels developed by
the ADL SAO .
PFES provides a moderate spectral resolution (about R=15000)
inside large spectral region.
The optical layout of PFES is presented
description of PFES (Postscript file, in Russian) is applied.

Selected spectra we derived with the PFES:
The spectrum of the protoplanetary candidate
IRAS04296+3429 (G0Ia, V=14.3)
Main parameters of the echelle-spectrometer PFES were improved
due to over 1998 its optical layout was essentially modified. It permits us,
in particular, to obtain spectra inside the blue spectral region, up to
3900 A. For example, recently we obesrved in this region the peculiar
star MWC 162
from the programme of A.Miroshnichenko (Pulkovo Observatory).
The spectrum of the fast evolving star
FG Sge in the deep minimum (1998,
June; V=15) we derived with the upgraded PFES.
