The QSI-6162 model camera model employs a KAF-16200, 16 megapixel, full frame CCD image sensor with microlens technology that has been specifically produced for astrophotography. The 6-micron pixel size make this camera the ideal imaging partner for a wide range of focal length telescopes. The ability to ‘bin’ the CCD means the QSI-6162 is suitable for focal lengths right up to 2.5m and still stay around 1 arc second per pixel (recommended for successful imaging). The large APS-H 16mp CCD sensor with a 35mm diagonal works happily using 2” mounted or 50.8 mm unmounted filters on scopes as fast as f/2.8 with minimal vignetting.

The ‘ws’ model comes with a shutter and filter wheel installed.
High Performance 16 Megapixel CCD image sensor

The 6162-model camera employs an On Semiconductor KAF-16200 16-megapixel full-frame CCD image sensor. The KAF-16200 sensor has a photoactive array of 4490 W x 3599 H pixels. Low dark current of 8e- and a 40,000e- well depth. Micro lenses cover the surface of the CCD to focus the light through the transparent gate to further increase the optical response of the sensor. The 6 µm sized pixels provides extremely high resolution at long focal lengths and superb wide field images at short focal lengths.

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.

The KAF 16200 sensor has excellent response values between 400nm and 1000nm with peak QE over 58%. Low dark current and high pixel charge capacity result in a dynamic range exceeding 69db. 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.

Refined Design

The new large format QSI 6162 sets new standards for full-featured, high performance scientific CCD cameras. The striking appearance, refined design and superior fit and finish only hint at the advanced technical performance inside. Some have described it as a work of art.

A defining feature of the 600 series camera is the flexible design that permits progressively configured body styles with a minimal impact on the overall size. The new 6162 case builds on this modular approach by adding an optional Off Axis Guider to the ‘ws’ style case without having to replace the whole case front as in the past. This helps to provides a cheap and easy upgrade path not available before with QSI cameras.

Engineered with extensive use of sophisticated CAD – CAM design tools, the QSI 6162 is machined from 6802 grade aluminium alloy. The finely finished anodized body components are assembled with corrosion resistant stainless-steel hardware throughout.

Keeping the depth of the camera to a minimum was an early design goal. The traditional short back focus measurements of the existing QSI 600 series cameras have been maintained with the design of the 6162. Not only is back focus minimized throughout the range, but the camera moment-arm is reduced resulting in greater stability. The shutter and filter wheel were placed inside the body, very close to the image sensor reducing back focus and overall depth. The motion control electronics are actually buried in the 3 mm thick shutter/filter mounting plate to reduce depth further. Pulling the cooling fans and heatsinks into the body resulted in another significant reduction in depth.
