CCD Detectors and Camera Electronics

G2 Mark II series of CCD cameras are manufactured with two kinds of CCD
detectors:

G2 cameras with OnSemi KAF Full Frame (FF) CCD architecture.
Almost all Full Frame CCD detector area is exposed to light. This is
why these detectors provide very high quantum efficiency. FF CCD
detectors, intended for research applications, are not equipped
with so-called Anti Blooming Gate (ABG – a gate, which prohibits
blooming of the charge to neighboring pixels when image is over-
exposed) to ensure linear response to light through the whole
dynamic range. FF CCD detectors used for astrophotography are
equipped with ABG to eliminate disrupting blooming streaks
within field of view.
Cameras with Full Frame, non-ABG detectors are suitable for
scientific applications, where linear response is necessary for
photometric applications in astronomy, microscopy etc. High
quantum efficiency could be used also for narrow-band imaging,
where overexposure is a rare exception, and for imaging of small
objects without a bright star in the field of view.
