Title:
METHOD FOR PRODUCING AN OPTICAL ASSEMBLY HAVING AT LEAST TWO OPTICAL FUNCTIONAL SURFACES ON A COMMON SUPPORTING STRUCTURE AND UNIT FOR CARRYING OUT THE METHOD
Document Type and Number:
WIPO Patent Application WO/2011/029634
Kind Code:
A3
Abstract:
The invention relates to a method for producing an optical assembly, comprising at least two optical functional surfaces (5, 6) arranged in a fixed positional relationship to one another on a common supporting structure (9), wherein by means of a processing machine (15), in various process steps, at least two optical functional surfaces (5, 6) and at least one reference structure (13) having a defined and measurable relative position to the optical functional surfaces (5, 6) are produced. The supporting structure (9) remains rigidly connected to the processing machine (15) until said process steps have been completed, and wherein the optical functional surfaces (5, 6) are then measured relative to the at least one reference structure (13), and any deviation from a target shape and target position is determined, after which said process steps are repeated at least once with modified actuation of the processing machine (15). The invention further relates to an optical device comprising an optical assembly produced in this way and to a unit for carrying out such a method.
