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.
Claims17
A reflector for an illumination source manufactured by a spin chuck having a etched surface, comprising:
- a. a body having a endless portion forming an endless outer surface and an endless inner surface, said body including an opening communicating with said endless inner surface, said endless inner surface further including a relatively fine pattern of depressions and protuberances derived from the etched surface of the spin chuck, to permit release of said body from the spin chuck and to scatter light from the illumination source.
A process for manufacturing a reflector for an illumination source utilizing a spin chuck having a surface comprising:
- a. etching a pattern on the spin chuck surface;
- b. rotating said spin chuck surface;
- and
- c. pressing a body of material against said rotating etched spin chuck surface to deform said body to conform to said etched spin chuck surface in order to produce a relatively fine pattern of depressions and ridges on a surface of said body derived said etched pattern on the spin chuck surface.
