QSI 683
The QSI 683 model camera employs an 8.3mp Kodak full-frame CCD image sensor with microlens technology. The increased Field of View, high quantum efficiency, wide dynamic range, dual read rates, low noise performance and internal 5 or 8-position color filter wheels make the QSI 683 ideally suited to a broad range of demanding scientific, medical, astronomical, and industrial imaging applications.
The compact design of the QSI 600 Series allows the 683 to set a new benchmark for cost and size in a high performance, full-featured scientific CCD camera. With optional features and upgradeability, the QSI 683 can be tailored to fit your needs today and in the future.
The QSI 683wsg is available with an Integrated Guider Port (IGP) allowing astronomers to guide using the light from the main telescope while picking off the light from the guide star in front of the filters.
The 683 camera system is supported by industry leading image acquisition software plus a full camera control API is available for creating custom Windows or Linux applications.
