confocal(redirected from confocally)
Also found in: Dictionary.
a microscope that allows the observer to visualize objects in a single plane of focus, thereby creating a sharper image (usually the objects are fluorescent molecules); a refinement of this microscope uses optic sectioning and a computer to record serial sections. This permits three-dimensional reconstruction.
