  3. Quantum Scientific Imaging - QSI RS 8.3ws-uv 8.3mp Cooled CCD Camera w/Mechanical Shutter & CFW

    Quantum Scientific Imaging - QSI RS 8.3ws-uv 8.3mp Cooled CCD Camera w/Mechanical Shutter & CFW

    How sensitive a CCD is to light is expressed as its Quantum Efficiency (QE). Higher QE means you can collect more photons in any given amount of time giving you better looking images with a higher Signal to Noise Ratio (SNR). The KAF-8300 sensor has a photoactive array of 3326W x 2504H pixels. It has excellent quantum efficiency between 350nm and 1000nm with peak QE over 60%. ... Learn More

    Quantum Scientific Imaging - QSI 620csg 2.0mp Cooled Color CCD Camera w/Integrated Guider Port

    Accurately recording the relative amount of light between different objects requires a camera that delivers a linear response to varying levels of light.  A CCD camera should record twice the photon flux from an object that is twice as bright.  Cameras that use CCDs with anti-blooming protection will start to show a drop in linearity as the pixels begin to approach a high percentage of full well capacity, but should be nearly linear at lower signal levels.
