focal plane — /ˈfoʊkəl pleɪn/ (say fohkuhl playn) noun 1. the plane normal to the principal axis of a lens (or system of lenses) or a mirror, which passes through the focal point. 2. the plane in which light rays from an external object are focused in a camera …
Focal length — The focal length of an optical system is a measure of how strongly it converges (focuses) or diverges (diffuses) light. A system with a shorter focal length has greater optical power than one with a long focal length. Thin lens approximation For… … Wikipedia
