About this product

Model:  qsi_683s
Part Number:  683s

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 colour 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.

Large 8.3mp Image Sensor

The large 3326×2504 sensor in the QSI 683, shown to the left approximately life size, provides unprecedented field of view in a camera using standard 1¼” filters.

The compact design and internal colour filter wheel of the QSI 683ws allows unvignetted, filtered images even with optical systems as fast as f/3. The 5.4µm pixel provides extremely high resolution for a high performance CCD.

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. Micro lenses cover the surface of the CCD to focus the light through the transparent gate to further increase optical response. See the Specifications tab below for more detail.

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.
