Optical Filters . WFPC2 features two solar-blind Wood's filters, for FUV (<2000 ) imaging. ... These Wood's filters have a broad bandpass from 1200 to 2100 with visible-light transmission lower than 10^-8. ... In such cases, a Wood's filter (or "solar blind" detector as on STIS) is essential for FUV imaging so that the visible light leak does not dominate the observation. ... Two similar Wood's filters (F160AW and F160BW) were mounted in SOFA wheel 1 to provide some redundancy. ...
