The series of developed products includes three types of CCDs – with 4K, 6K, and 12K pixels.
CCDs have crystals (chips) of big size (~10cm) and high parameters. This requires the development of modern high effective CCD transfer registers, providing charge transfer for distance( ~ 5 cm) with transfer inefficiency not worse than 0,999998.
Application
– systems of space base;
– small object registration devices;
– facsimile systems of high resolution;
-multispectral systems.
