Absolute Quantum Efficiency
See the Kepler page for details and alternate configurations.
The KL4040 FI scientific CMOS camera has the same imaging area as the KAF-16803 CCD, but with a fraction of the noise even at multiple frames per second. Kepler cooled sCMOS cameras provide ultra-high sensitivity, ultra-low noise, and high frame rates, all at game-changing price to performance ratio.
