摘要:
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.

摘要:
The invention relates to a method and a device for the interferometric testing of the shape and/or position of at least two optical functional surfaces (13, 14) using an interferometric testing structure comprising an interferometer (9), a beam-shaping optical element (1), and alignment marks (15, 16, 17, 18). The beam-shaping optical element (1) is used to generate alignment wave fronts and testing wave fronts which are transmitted to or reflected at the alignment marks (15, 16, 17, 18) and/or the optical functional surfaces (13, 14), whereby measurement wave fronts are generated. The method and the device allow a measurement of the position of the optical functional surfaces (13, 14) with respect to one another and/or with respect to the alignment marks (15, 16, 17, 18) and a determination of shape and/or positional deviations of the optical functional surfaces (13, 14) from the target geometry and/or position of said surfaces by analyzing the measurement wave fronts in the interferometer (9).
