Abstract
A reflector for an illumination source manufactured by a spin chuck having an edge surface. The reflector includes a body having a contiguous portion composed of an endless outer surface and a reflective endless inner surface. The body further includes an opening communicating with the endless inner surface. The endless inner surface possesses a relatively fine pattern of depressions and protuberances derived from an edged surface of the spin chuck. The edge surface permits release of the body from the spin chuck although the body may be formed into a rounded or curved member.
