Overview
The CCD207 is a spectroscopic format sensor in the L3VisionTM range of products from e2v Technologies. This device uses a novel output amplifier circuit that is capable of operating at an equivalent output noise of less than one electron at pixel rates of over 15 MHz. The sensor converts photons to charge in the image area during the integration period, then transfers this charge into the readout register. Following transfer through the readout register, the charge is multiplied in the gain register before conversion to a voltage by an output amplifier.
The sensor can also operate in inverted mode to suppress dark current, as this is now the dominant noise source (even at short integration times). This makes the sensor well suited to high readout rate spectroscopic imaging, particularly when the focal plane irradiance is low.
