Claim Text:
1. A method for producing a micromechanical component, the method comprising: providing a substrate having a first outer surface and a second outer surface, which faces away from the first outer surface; forming a through-hole through the substrate from the first outer surface of the substrate up to the second outer surface of the substrate, such that a first opening of the through-hole is enclosed by the first outer surface of the substrate, and a second opening of the through-hole is enclosed by the second outer surface of the substrate; attaching an optical functional layer on the second outer surface of the substrate, wherein the optical functional layer covers the second opening of the through-hole; removing a first segment of the substrate that includes the first opening of the through-hole on the first outer surface of the substrate so that there arises a third outer surface that is inclined relative to the second outer surface of the substrate, the third outer surface facing away from the second outer surface of the substrate, the inclined third outer surface enclosing a third opening of the through-hole; and separating the micromechanical component by separating a first part of the substrate, which includes the through-hole, from a remaining part of the substrate, and separating a second part of the optical functional layer, which is attached to the first part, from a remaining part of the optical functional layer.
