e2v CCDs Upgrade Hubble Telescope Imager

Space Daily: e2v CCD will equip Wide Field Camera 3 (WFC3), a new instrument that will be installed on Hubble. Its key feature is the ability to span the electromagnetic spectrum from UV, through visible light and into NIR. The UVIS channel of the instrument is equipped with e2v's close-butted pair of CCD-43, forming an array of 4k(H) by 2k(V) 15um pixels. It features enhanced UV QE and back-illumination to give a very broad waveband response. The typical quantum efficiency is 50% at 250nm and 65% at 500nm. The low noise output amplifiers provide typical noise of ~2.5 e-rms at 50kHz.
