The Rayleigh Criterion for Microscope Resolution

WebThe number of electrons that can accumulate in the potential well before their charge exceeds the applied electric field is known as the full well capacity. The full well capacity depends on pixel size. A typical full well capacity for CCDs used in fluorescence microscopy is between 20,000 and 40,000 photons.
