As STIS filters are located in the STIS slit wheel they must be listed as apertures in Phase II proposals and cannot be used in combination with other apertures. The STIS filters can, however, be used together with a grating to do filtered slitless first order spectroscopy. This can be especially useful when it is necessary to exclude contamination due to geocoronal lines.

STIS has a relatively limited set of filters. However its imaging capabilities do include some unique advantages that make it worth considering as an alternative to ACS for some UV and optical imaging projects.

Below are tables summarizing the filters available for each STIS detector. For more information, please see the STIS Instrument Handbook.
