Overview
This version of the CCD42 family of CCD sensors has full-frame architecture. An extremely low noise amplifier makes the device well suited to the most demanding applications, such as spectroscopy. To improve the sensitivity further, the CCD is manufactured without anti-blooming structures. This variant of the CCD42-10 operates in advanced inverted mode (AIMO) for use at Peltier temperatures. e2v technologies' AIMO structures give a 100 times reduction in dark current with minimum reduction in full-well capacity.
The output amplifier is designed to give excellent noise levels at low pixel rates, and can match the noise performance of most conventional scientific CCDs at pixel rates as high as 3 MHz.
The readout register has a gate controlled dump drain to allow fast dumping of unwanted data. The register is designed to accommodate four image pixels of charge, and a summing well capable of holding six image pixels is provided. The output amplifier has a feature enabling the responsivity to be reduced to allow the reading of such large charge packets.
