Product Details

  • The QSI 683wsg CCD camera employs the popular 8.3-megapixel Kodak (now TrueSense) full-frame CCD imaging sensor. The KAF-8300 offers a large field of view in cameras using standard 1.25-inch filters. The 5.4 um pixel size provides extremely high resolution. The sensor uses true two-phase charge transfer technology with a transparent gate that significantly increases optical response compared to traditional front illuminated full-frame sensors. The superb imaging performance of the 683 WSG camera is wrapped in an attractive, compact design with outstanding power efficiency and investment protecting upgrade-ability. The refined engineering and impressive fit, finish, and attention to detail will surpass your highest expectations. The QSI 683wsg camera system is supported by industry-leading astronomy and microscopy image acquisition software, and a full camera control API is available for creating custom Windows or Linux applications.

    QSI 683WSG CCD Camera Highlights:

    • The QSI 683 camera comes with a TrueSense KAF-8300 sensor, with 8.3MP and a peak QE of 60-percent
    • All WSG models include an Integrated Guider Port (IGP)
    • An 8-Position Color Filter Wheel comes ready for your threaded 1.25-inch filters
    • High-speed USB 2.0 with 16-bit output
    • Dual read rates of 800kHz and 8MHz with virtually undetectable read noise
    • Electronic shutter speeds to 100 microseconds
    • Internal, even-illumination mechanical shutter for dark and bias frames
    • Intelligent, programmable two-stage TEC cooling to 45-degrees C below ambient
    • ASCOM-compatible Windows COM API
    • Linux drivers and API

    About the KAF-8300 Imaging Sensor: The QSI 683wsg camera employs a Kodak KAF-8300 full-frame CCD image sensor with micro-lensing technology. The KAF-8300 has excellent quantum efficiency between 350 nm and 1000 nm with a peak QE of 57-percent. Low dark current and high pixel charge capacity result in a dynamic range exceeding 70db. The sensor has anti-blooming protection and a fast electronic shutter. Microlenses cover the surface of the CCD to focus the light into each 5.4-micrometer pixel, thereby increasing the optical response.

    About QSI Two-Stage TEC Cooling: The QSI 683wsg has a very efficient custom 2-stage thermoelectric cooler (TEC) subsystem. Intelligent, programmable cooling fans are integrated into the rear of the camera body to remove the heat generated by the cooler. Typically, forced air cooling lowers the regulated CCD temperature by up to 45-degrees C below ambient utilizing 85-percent power. Tight +/- 0.1-degrees C temperature regulation is maintained at temperature settings of 10-degrees C below ambient and lower. A slim liquid heat exchanger (sold separately) can be attached to the rear of the camera body to increase the cooling further, up to 55-degrees C below the temperature of the circulating fluid.

    The cooled CCD image sensor is positioned in a hermetically sealed environmental chamber and covered with an anti-reflection precision optical window. The sealed chamber is purged with an ultra-dry noble gas to increase heat conduction and eliminate the possibility of frost forming inside the chamber. To extend the useful period before re-purging is required, a user-rechargeable micro-sieve desiccant is employed to scavenge water molecules that enter the chamber. It is located behind a sub-micron, gas-permeable membrane to prevent particulate contamination of the CCD chamber.
