Developed for the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) which contains four Teledyne e2v CCD43-82 CCD image sensor. There are two channels in the telescope - Ultraviolet-Visible (UVIS) channel or the Near-Infrared (NIR) channel. The UVIS channel of the instrument is equipped with e2v’s large CCD43-82 image sensor. The full frame imaging CCD is designed to operate in Inverted Mode for low dark signal. Features include enhanced Ultra-Violet (UV) quantum efficiency and back-illumination to give a very broad waveband response. Designed and packaged for assembly in close-butted pairs, thus creating approximately a 4k square pixel image area.
The high responsivity and very low noise output amplifiers, typically ~2.5 e-rms at 50kHz, enable imaging of feint objects. A parallel charge injection structure permits mitigation against radiation effects of the space environment and a supplementary “notch” or mini-channel is included to further reduce the impact of irradiation when imaging at small signal levels.
Notably the Near-Infrared (NIR) channel detectors where produced by Teledyne Imaging Sensors consisting of a H1RG 1024 x 1024 18µm HgCdTe focal plane arrays (FPAs).
