Abstract
A process for forming parabolic micro-reflectors on an object includes the steps of placing the object proximate to a transfer lens system, shining a laser beam through the lens system, a mask and a wobble plate and onto the object, the wobble plate wobbling the laser beam such that a parabolic shaped micro-reflector is formed on the object.
