The SCORPIO-2 project: Spectral Camera with Optical Reducer for Photometric and Interferometric Observations - 2 |
Broad-band filters
The 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 glass filters transmission curves are shown by solid line. The measurements were done with the SCORPIO-2/VPHG940@600. The dashed lines indicate the same curves when the CCD EEV 42-40 sensitivity curve was taken into account.
The SDSS (ugriz) glass filters with anti-reflective coating made by Asahi Spectra USA Inc. are also available for direct imaging observations.
The SDSS filters transmission curves are shown by solid line, the manufacturer data. The dashed lines indicate the same curves when the CCD EEV 42-40 sensitivity curve was taken into account.
intermediate-band filters
The set of passband filters with band width 70-200 A is available for observations in the Н-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 narrow band filters for observation with scanning FPI
The sets of narrow-band (FWHM=12-25 A) filters are available for observations of galaxies in the [OIII], H-alpha, [NII], [SII] emission limes. You can use this IDL-program to choose the optimal filters for desired systemic velocities.
