Precision All-Metal Reflectors for Use with Projection Arcs

C. E. Shultz

All reflecting surfaces used for present-day projection purposes are metal. In the well known glass type of reflector, the silver layer acting as the reflecting surface is supported by a base of glass, which acts also as a protecting medium against the damaging effects of an open arc and its associated heat. In the all-metal type of reflector, both the supporting base and the reflecting surface are, as may be expected, composed of metal.
