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 e2v technologies back-thinning process ensures high quantum efficiency over a wide range of wavelengths, with a 90% typical peak response.
The device functions by converting photons to charge in the image area during the integration time period, then transferring this charge through one of the image and store sections into the readout register. Following transfer through the readout register, the charge is multiplied in the gain register prior to conversion to a voltage at the output amplifier. The multiplication gain may be varied by adjustment of the multiplication phase clock amplitude RØ2HV.
The device is supplied in a sealed integral Peltier package, which provides a nominal operating chip temperature of 233 K (-40 °C).
A variant of this device is also available with an integral shutter (CCD219). Consult e2v technologies for further information.
