Webany surface including those free from constraints of symmetry and/or form Note 1 to entry: A general surface can be both a continuous as well as a discontinuous surface. It can contain local regular geometrical properties. WebThe shape, size, and location of fiducials are dependent on the shape of the o ptic, measurement methodology, blocking, manufacturing process, and other factors. As long as the fiducials provide a repeatable reference point from which measurements can be made, they may manifest in many different forms. For freeform optics it may be necessary to
