The QSI 583wsg camera employs a Kodak KAF-8300 8.3 megapixel full-frame CCD image sensor with microlens technology. The KAF-8300 sensor has a photoactive array of 3326W x 2504H pixels. It has excellent quantum efficiency between 350nm and 1000nm with peak QE over 60%. Low dark current and high pixel charge capacity result in a dynamic range exceeding 70db. The sensor employs a true two-phase charge transfer technology with a transparent gate that significantly increases optical response compared to traditional front illuminated full frame sensors. Micro lenses cover the surface of the CCD to focus the light through the transparent gate to further increase optical response. The QSI Model 583wsg camera incorporates the internal mechanical shutter, internal color filter wheel and the integral off-axis guider in a body that is just a big larger than the "full" body of the ws models (4.45" x 5" x 3"). The shutter is not only used for timing exposures, but can be left closed to produce 'dark frames' for subsequent image processing. Exposures can be as short as 0.03 seconds or as long as 240 minutes. The filter wheel accepts any standard 1.25" filter set. Optionally, the camera can be supplied with the Astronomik LRGB Filter Set, which will be installed in the clean room environment at QSI (click the "Accessories" tab for filter options). The filter wheel can easily be removed and replaced to change or clean the glass filters.
