s a 4096(H) x 4097(V) solid state Charge Coupled Device (CCD) full frame sensor. The CCD is intended for advanced scientific, space, industrial, and commercial digital imaging applications. The CCD486 active area is organized as an array of 4096 horizontal by 4097 vertical imaging elements. The pixel pitch is 15µm with a 100% fill factor. For dark reference, each readout line is preceded by 18 dark pixels. The imager is available in front-illuminated as well as back-illuminated configuration. A split readout architecture has been adopted to facilitate high data rates with simultaneous readout from four output ports, and provides the flexibility to read out the entire image frame from two output ports, or from a single output port to simplify the drive electronics requirements
