Method for producing an optical assembly having at least two optical functional surfaces, an optical device and unit for carrying out the method

A method for manufacturing an optical arrangement with at least two optical functional surfaces of a defined shape which are arranged on a common support structure in a fixed positional relation to one another, comprising:

• in a first process step, by way of a machine tool, a first optical functional surface with a shape defined by an activation of a machine tool is manufactured from a blank which is at least one of formed by the support structure and arranged on the support structure,
• in a second process step, by way of the machine tool, least one second optical functional surface with a shape defined by the activation of the machine tool and with a defined relative position to the first functional surface is manufactured from at least one of the mentioned blank and a further blank which is arranged in the support structure, and
• in a third process step, by way of the machine tool, at least one reference structure with a defined and measurable relative position to the optical functional surfaces is at least one of manufactured upon the support structure, manufactured on the support structure, manufactured on the blank and manufactured on the further blank, wherein the support structure remains fixedly connected to the machine tool until completion of the mentioned three process steps which may be carried out in at least one of a temporal sequence and simultaneously;
• and
• wherein subsequently the shape and the position of the at least two optical functional surfaces on the support structure relative to the at least one reference structure is measured in a measurement construction and a deviation of the optical functional surfaces from a desired shape or desired position, which is defined in an exact mariner relative to the at least one reference structure, is determined,
• wherein the mentioned three process steps are repeated at least once with an activation of the machine tool which is changed in a manner such that the mentioned deviation is reduced.
