  • QSI 628s is built on the Sony ICX674 monochrome sensor.
  • Feature high sensitivity with peak QE of over 75%.
  • Frame rates up to 100 microseconds.
  • Dual read rates of 800kHz and 8MHz.
  • USB 2.0 16-bit high speed output.
  • Medium profile body is compact and lightweight.


Based on a 2.8MP Sony ICX674 monochrome sensor, the QSI 628 offers exceptional sensitivity with a peak QE of over 75%. This sensitivity is paired with wide dynamic range, dual read rates, and low noise.  The 628 series is well suited for a wide range of applications including planetary and deep sky imaging.   The 628i features an electronic only shutter, for very high frame rates up to 100 microseconds.

The QSI 600 Series builds on the foundation of the popular QSI 500 Series. Dual read rates of up to 8 MHz with high-speed USB 2.0 and full 16-bit output allow 600 Series cameras to produce high quality images with high frame rates, extremely wide dynamic range, excellent linearity and exceptionally low noise. Cooling on the 600 Series is achieved with a custom 2-stage TEC supporting regulated cooling to greater than 45C, or greater than 50C with the option Liquid Heat Exchanger.

The superb imaging performance of 600 Series cameras 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.

QSI 600 Series Body Design

Small and sleek, the QSI 600 series is nearly small enough to hide behind a CD-ROM.  Refined design with precision machined and fit parts, the cameras are also striking in a metallic black and blue finish.  With the goal of maintaining as shallow of a depth as well as overall size, the shutter and filter wheel (where included) have been placed very near to the image sensor.  This results in minimized backfocus and as compact of a body as function will allow.  This reduced design also results in great stability thanks to a shortened moment-arm.  The motion control electronics are actually buried in the 0.12" 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. Finally, having all electrical cables and the optional liquid heat exchanger recirculation hoses exit the body in the same direction and perpendicular to the optical axis insured an interference-free fit in tight spaces.   Each body is machined out of aircraft-grade aluminum, finely finished with a corrosion resistant anodized finish and stainless steel hardware.

The 628s features the medium body profile.  At just 2 pounds 2 ounches and only 2" deep, all of the QSI 600 cameras (with the exception of 8 position filter wheel models) are a mere 4.45" square.  They are highly compact and portable. Their compact design also ensures that a QSI 600 camera will not weigh your setup down, meaning less counterbalance is required and focusers perform better with less stress.
