​Overview

The CCD220 is an L3Vision™ sensor designed for very high frame rate and low signal applications such as wavefront sensing or adaptive optics.

The image area is split into two half sections for split frame transfer operation using metal-buttressed electrodes for high speed. The image section can be operated in inverted mode if desired.

The device uses eight output amplifier circuits that are capable of operating at an equivalent output noise of less than one electron (rms) at frame rates of >1.2 kHz. All outputs must be used for full image read-out.

The Teledyne e2v back-thinning process ensures high quantum efficiency over a wide range of wavelengths, with a >90% typical peak response.
