Abstract
An optical assembly for an optical sensor device has a lens plate, a light source, and a light receiving unit. The lens plate includes a lens structure on a side associated with the light source and a light extraction structure on a side facing away from the light source. The lens structure has different local radii of curvature.

An optical assembly for an optical sensor device of a motor vehicle, comprising:
- a lens plate;
- a light source;
- and
- a light receiving unit,
- wherein the lens plate includes a lens structure on a side associated with the light source and a light extraction structure on a side facing away from the light source, the lens structure having different local radii of curvature.
A method of manufacturing an optical assembly that includes a lens plate, a light source, and a light receiving unit, wherein the lens plate includes a lens structure on a side associated with the light source and a light extraction structure on a side facing away from the light source, the method comprising:
- specifying a focal length and a transmission function of the lens structure;
- and
- determining a curvature function that describes the local curvature of the lens structure;
- wherein the curvature function is such that a power density of light coming from a focal point of the lens structure and passing through the lens structure corresponds to the specified transmission function.
