The Space Telescope Imaging Spectrograph (STIS) incorporates three 1024 x 1024 array detectors to observe the wavelength range of 115 to 1000 nm in a versatile combination of spectroscopic and imaging modes. Ultraviolet wavelengths are covered by two photon-counting Multi-Anode Microchannel Array (MAMA) detectors developed by Ball Aerospace Technologies Corporation; near-UV and visible wavelengths are covered by a UV-enhanced, backside-illuminated CCD developed by Scientific Imaging Technologies, Inc. Pre-Flight Calibration of STIS has recently been completed. We report here on the performance measured for the three detectors in areas such as sensitivity, resolution, noise, linearity, flat field behavior, stability, and dynamic range.
