ST-2000XM CCD Camera

The Kodak KAI-2020M is a high-performance multi-megapixel image sensor designed for a wide range of scientific, medical imaging, and machine vision applications. The 7.4 mm square pixels with microlenses provide high sensitivity and the large full well capacity results in high dynamic range. The vertical overflow drain structure provides antiblooming protection, and enables electronic shuttering for precise exposure control to 0.001 seconds. Other features include low dark current, negligible lag and low smear. The KAI-2020M CCD is a 2 megapixel progressive scan detector with an active image area of 1.92 million pixels. The active image area is 1600 x 1200 pixels. This array is 75% larger than the Sony CCD used in competitors' "megapixel" cameras, nearly as large as an ST-8XME, and the ST-2000XM is a self-guiding camera, utilizing SBIG's patented dual sensor design. Although the imaging CCD is nearly the same size as the KAF-1603ME used in the ST-8XME, due to the smaller pixel size it contains nearly half a million more pixels than the ST-8XME.
