FLI Kepler Back Illuminated GSENSE4040BSI CMOS Camera

The KL4040 BI scientific CMOS camera has the same pixel size and imaging area as the popular KAF-16803 CCD, but with 1/4 the noise, 90% peak quantum efficiency, and excellent sensitivity in the UV. Kepler cooled sCMOS cameras provide ultra-high sensitivity, ultra-low noise, and high frame rates, all at game-changing price to performance ratio.
