ABSTRACT:
Large projection screens, of which planetarium domes are typical, may conveniently be made up of a plural of prefinished panels, at least one edge of at least some of which panels overlaps another panel in a lap joint construction so that edges of the panels have a minimal effect upon light directed upon the screen from any angle. Panel edges overlapping another panel are tapered from a generally uniform thickness to substantially reduced thickness at the edge in a relatively short distance compared to panel dimensions and made to conform to and lay against the other panel. The panels are preferably made by a method which may involve either first shaping or finishing the projection surface of the dome panel. Each edge which will overlap another panel is then chamfered on the surface opposite the finished surface to form the taper. Finally the chamfered edge is deformed so that it will lay against and conform to the panel which it overlaps.
