Abstract
Systems, methods, and devices for identifying a reference focal surface in connection with light microscopy. A method includes identifying a fiducial marker printed on a surface of a coverslip or a slide used in connection with optical microscopy. The method includes focusing the optical microscope on the fiducial marker to calculate a focal distance of the fiducial marker. The method includes calculating a reference focal surface defining the surface of the coverslip or the slide based on the focal distance of the fiducial marker.
