​Overview

The CCD250-82 is a split frame sensor with an image area of 4096 x 4004 pixels and 16 outputs for faster readout. Back illumination technology, in combination with an extremely low noise amplifier, makes the device well suited to the most demanding applications, such as astronomy.

The ‘High-Rho’ technology is used to increase the thickness of the silicon to extend the response significantly at the infra-red end of the spectral range. The device operates in the same manner as other Teledyne e2v sensors, but with additional back-substrate bias voltage to fully deplete the silicon. Details are given at the end of this datasheet.

The device is supplied in a package designed to facilitate the assembly of large close-butted mosaics used at cryogenic temperatures. The design of the package ensures that it is 4 sides buttable and that the device flatness is maintained at the working temperature.

Designers are advised to consult Teledyne e2v should they be considering using CCD sensors in abnormal environments or if they require customised packaging or performance features.
