During the most recent WFC3 thermal vacuum (TV) testing campaign, several tests were executed to measure the UVIS channel throughput through its filters. These tests complement the tests of the UVIS channel system throughput, which is done without a filter in the beam. The UVIS filter transmissions were already well-characterized by scans of the filters at JPL and GSFC, so the filtered tests here are geared toward verification instead of characterization. Each of the filters was checked at a single in-band wavelength, showing good agreement with previous scans. Additional tests checked the red leak performance in several UV filters, and the red end cutoff of the F850LP, which is determined by the detector instead of the filter. The red leak checks at 450 nm and 600 nm in the F343N and F336W filters failed, likely due to scattered light in the single monochromator mode of the optical stimulus, but this should be verified in the next TV campaign.
