This version of the CCD42 family of CCD Sensors has full frame architecture. Back illumination technology in combination with an extremely low noise amplifier make the device well suited to the most demanding applications such as astronomy. The output amplifier is designed to give excellent noise levels at low pixel rates and can match the noise performance of most conventional science CCDs at pixel rates as high as 1 MHz. The design of the package permits easy housing to cold shoes or supports. The CCD42-20 is also available in front illuminated format or on a metal package designed for close butting.
