QSI 520wsg Monochrome Cooled Interline CCD Camera 520WSG

About this item

The QSI 520wsg camera employs a Kodak KAI-2020M 2 megapixel interline transfer CCD image sensor with microlens technology. The KAI-2020M sensor has a photoactive array of 1600W x 1200H pixels. It has excellent quantum efficiency between 350nm and 1000nm with significant enhancement at the blue end of the spectrum. Low dark current and high pixel charge capacity result in a dynamic range exceeding 74db. The sensor employs a vertical overflow drain that provides both antiblooming protection and a fast electronic shutter. Micro lenses cover the surface of the CCD to focus the light into each pixel to increase optical response.

The QSI Model 520wsg 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. The filter wheel can easily be removed and replaced to change or clean the glass filters.
