Broad-band filtersThe broad-band glass filters made in SAO RAS are used for the observation in the Johnson-Cousins (UBVRI) photometric system in the direct images mode.
The SDSS (ugriz) glass filters with anti-reflective coating made by Asahi Spectra USA Inc. are also available for direct imaging observations.
Intermediate-band filtersThe set of passband filters with band width 70-200 A is available for observations in the H-alpha, [SII], [OIII] emission line and in the continuum. The majority of the filters were made by Asahi Spectra USA Inc., the FN674 filter was made by NIIPP (Moscow).
The set of passband filters with band width ~250 A is available for observations emission lines, continuum and to study spectral energy distribution (SED). These filters were made by Edmund Optics..

The set of passband filter cut spectral range in observations in IFU mode was made by Asahi Spectra USA Inc..
The IFU filters transmission curves.

N.N. Kisilev (MAO, Kiev) kindly provide the set of intermediate-band filters for observations of the emission bands in comets.
The filters transmission curves of the `comets' filters measured with the SCORPIO-2 in the F/4 beam.
