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.
