The ST-4000XCM uses a large 4.2 megapixel KAI-4022CM color CCD and has 2048 x 2048 pixels at 7.4 microns square (15.2 x 15.2 mm). This is the same size CCD used in the STL-4020 camera. The KAI-4022CM comes in a single class without column defects. The 7.4 mm square pixels with microlenses provide high sensitivity. The vertical overflow drain structure provides antiblooming protection, and precise exposure control to 0.001 seconds. Other features include low read noise, low dark current, negligible lag and low smear. This CCD uses a high gain output amplifier that reduces the read noise by almost half compared to previous versions.
