Optical component with beam deflection element, method for production thereof, and beam deflection elements suitable for the component

Abstract

The present invention relates to an optical component, comprising a substrate having a substrate surface (), a radiation output element () situated on the substrate surface and/or a radiation input element () situated on the substrate surface and a beam deflection element () having dimensions of below 1 mm in all three spatial directions, which optical component is arranged on the radiation output or input element () on the substrate surface () and designed such that it deflects electromagnetic radiation exiting the radiation output element () substantially vertically with respect to the substrate surface () and in so doing forms a beam that has a smaller or even negative angle in comparison with the exit angle that the beam leaving the radiation output element forms with the substrate surface or is oriented parallel to the substrate surface, or that it focuses electromagnetic radiation entering the beam deflection element () at a particular angle with respect to the substrate surface and directs it into the beam input element, wherein the beam deflection element () has an entry area for entering radiation and an exit area for this radiation and has at least two areas influencing the path of the radiation passing through the element, one of said areas causing a deflection in at least some of the incident radiation and the other causing the beam divergence and/or the beam form to change, wherein at least one of the entry and exit areas of the beam deflection element is in planar form, characterised in that this planar area is located at least to some extent directly on an exit or entry area of said beam output or input element. The invention also relates to a method for producing this component and to beam deflection elements suitable therefor.
