About the QSI 620 CSG Monochrome CCD Camera

The QSI 620csg CCD camera uses a 2.0 megapixel Kodak (now TrueSense) interline transfer Color CCD imaging sensor as its light-gathering source. The KAI-2020C has excellent quantum efficiency between 350nm and 1000nm with significant enhancement at the blue end of the spectrum. Micro lenses cover the surface of the CCD to focus the light into each 7.4um pixel to increase optical response. The superb imaging performance of the 620 CSG camera is wrapped in an attractive, compact design with outstanding power efficiency and investment protecting upgradeability. The refined engineering and impressive fit, finish and attention to detail will surpass your highest expectations.The QSI 620csg 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.

About the KAI-2020C Imaging Sensor

The QSI 620csg camera employs a Kodak KAI-2020 interline transfer One Shot Color CCD image sensor with micro-lensing technology. The KAI-2020C 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 results in a dynamic range exceeding 74db. With the fast electronic shutter and 8MHz High Speed read mode, the QSI 620 can produce frame rates of up to 20 frames per second (fps) when reading a Region of Interest (ROI), or 9 fps for low resolution full-frame 16-bit images.

About QSI Two-Stage TEC Cooling

The QSI 620csg 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°C below ambient utilizing 85% power. Tight +/- 0.1°C temperature regulation is maintained at temperature settings of 10°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°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.

QSI Integrated Guide Port WSG Upgrade

The QSI 600 Series CSG cameras provides a solution to the problems normally associated with guiding by integrating a Guider Port directly into the camera body. The pick-off prism is designed to sit in front of the filters so that you will always have all the star's light available for guiding.

The large 1/2” square pick-off prism of the integrated guide port is optimally positioned close to the internal filter wheel, supporting the use of guide cameras with large sensors, while preventing any vignetting of the main sensor, even with very fast optical systems. The Integrated Guide Port (IGP) is designed to support any camera with 12.5mm of back focus or less that can be attached using C-mount or T-mount threads.

The threaded adapter sits on top of the focus ring and allows the guide camera to be rotated to any position. The focus ring threads onto the focus base to allow 3mm of travel when focusing the guide camera. Once focus is achieved, the focus ring is locked with a set screw. The guide camera can still be rotated manually if desired without changing the focus. The end result is a rigid, easily focused guide camera that will not move or flex while your mount tracks the apparent motion of the night sky.
