Specifications
G3 and G4 series of CCD cameras are manufactured with two kinds of
Truesense Imaging (formerly Kodak) CCD detectors:
● G3 and G4 cameras with Truesense Imaging 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 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.
