Comparison of the electron multiplying charge-coupled device (EMCCD) and scientific complementary metal-oxide-semiconductor (sCMOS) cameras for use with a spinning disk confocal microscope. Adjacent cells were imaged, making use of either an EMCCD or sCMOS camera, using different tube lenses such that the pixel size in the image plane was the same for both (16-μm pixels for the EMCCD, with a 125-mm tube lens; 6.5-μm pixels for the sCMOS, with a 50-mm tube lens).
