pixel size The physical size of individual pixels on an image sensor. Related MicroscopyU Article Matching Camera to Microscope Resolution The ultimate resolution of a charge-coupled device (CCD) or complementary metal oxide semiconductor (CMOS) image sensor is a function of the number of photodiodes and their size relative to the image projected onto the surface of the imaging array by the microscope optical system. When attempting to match microscope optical resolution to a specific digital camera and video coupler combination, use this calculator for determining the minimum pixel density necessary to adequately capture all of the optical data from the microscope.
