LOW-STRESS JOINING METHOD, AND ASSOCIATED OPTICAL COMPONENT

摘要

The invention relates to a low-stress joining method which is particularly suitable for producing thin optical components comprising high-precision planar optics. The wavefront aberration of the mounted assembly does not differ from the sum of aberrations of the individual components, i.e. the joining process does not deteriorate the continuous wavefront of the optical beam. The invention further relates to an optical component assembly which ensures that no optical cement is located between the functional optical surfaces of the individual optical elements that are to be positioned and which is suitable for a thin design. For this purpose, it is essential for the assembly to comprise A) a planar optical unit (1) encompassing a delay or filter plate (2) that is glued to form a subassembly and is connected to the planar optical unit (1) only at the outer edge thereof, and B) an optical unit (4) which is connected to the subassembly by means of three spacers (3) in such a way that the three spacers (3) lie outside the optical test range.
