WebIf 77 of every 100 incident photons of λ = 530nm are likely to be detected, then the QE at 530nm is estimated to be 77%. A QE curve is a graph of the Quantum Efficiency vs. wavelength. The following is an interactive plot of the QE curves for cameras based on sCMOS and CMOS imagers. They are shown on one rather crowded graph for comparison.
