A special full frame CCD imager has been developed for high performance applications. The device A-1059 type consists of 256(H)* (2*144)V elements and is fabricated using a triple ply, p-channel CCD process. The pixel size is 18 micrometers *24 micrometers . The device A-1131 type consists of 230(H)* (3*144)V elements and is fabricated using a triple poly, buried n- channel CCD process. The pixel size is 24 micrometers *27 micrometers . Its antiblooming efficiency is 500 saturation exposure.
