The QSI 6120 model camera employs a 12mp Sony CCD image sensor. This new generation of Sony sensors offers remarkable sensitivity with a peak QE of over 75%. The high sensitivity, wide dynamic range, dual read rates, low noise performance, and internal 5 or 8-position color filter wheels make the QSI 6120 ideally suited to a broad range of demanding scientific, medical, astronomical, and industrial imaging applications. The 6120 camera system is supported by industry-leading astronomy and microscopy image acquisition software plus a full camera control API is available for creating custom Windows or Linux applications.

High-Performance CCD Image Sensor

The 4250×2838 sensor in the QSI 6120i provides extremely high resolution with its 3.1µm pixel. The QSI 6120i camera employs a Sony ICX834 12 megapixel interline transfer CCD image sensor with microlens technology. The Sony ExView sensor has exceptional sensitivity across the visual band with a peak quantum efficiency of 77% along with a remarkably low dark current. The sensor has antiblooming protection and a fast electronic shutter. Microlenses cover the surface of the CCD to focus the light into each 3.1µm pixel to increase optical response.

High-Performance Design

Two separate analog processing chains, providing dual read rates, allow the QSI 600 Series to meet two seemingly incompatible imaging goals. The QSI 600 Series High-Quality mode provides the highest possible Signal to Noise Ratio (SNR) for applications that require the lowest noise and widest possible dynamic range. The high-Speed mode has a read rate of 8MHz providing high speed reads at multiple frames per second. The read mode is easily changed under program control providing exceptional flexibility in tuning the camera’s performance to the desired imaging goals.

Innovative, Aesthetic Body Design

Small enough to practically hide behind a CD-ROM, the medium format QSI 600 Series family 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 lurking inside. Some have described it as a work of art.

Efficient, Low Power CCD Sensor Cooling

Key in the compact design of the 600 Series cameras is 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 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.
