    The Kepler Series is a giant step forward in throughput, providing faster digitization, higher speed interfaces, and up to 35 channel readout. Sensors to be supported include front and back illuminated sCMOS, interline transfer CCDs, and EMCCDs.

    The KL4040 scientific CMOS camera has the same pixel size and imaging area as the popular KAF-16803 CCD, but with half the noise and 40% higher quantum efficiency. Kepler cooled sCMOS cameras provide ultra-high sensitivity, ultra-low noise, and high frame rates, all at game-changing price to performance ratio.
