SAM Adaptive Optics Module Imager (SAMI) filters (3 x 3 inches square)
SAMI has one filter wheel with 7 positions for 3 inch square filters. The SAMI Filter page lists the characteristics of the two new broadband filter sets, plus an assortment of narrow band filters, which have been specifically designed and built for use on SAMI: a Kron-Cousins BVRI set, a SDSS griz set, and Ha, NI, [NII] and [SII] narrow band filters, in addition to several redshifted Ha filters designed for the Fabry-Perot module (more details in this link). Any of these filters are readily available for use with SAMI. Additional 3x3 inch filters from the CTIO filter stock (click here) can also be requested.

CTIO Imaging Filters
CTIO has an extensive collection of filters, including 4x4, 3x3 and 2x2 inch filters, that can be used in SOI with adapter frames. Information on the CTIO filters and their characteristics can be found here. These filters can generally be borrowed for use for imaging on SOAR, although older filters may need testing to confirm that their performance is acceptable.
