Claim 0:
1. An optical system for a LIDAR device, comprising:
a lens array including a multitude of convex microlenses on a single shared substrate, each of the convex microlenses having a flat surface and a convex surface, wherein an entirety of the lens array is shaped in a concave shape and the multitude of convex lenses includes at least six convex microlenses;
a lens system configured to deflect beams out of a scanning area or into the scanning area, the lens system being situated in a beam path of the beams between the scanning area and the lens array; and
at least one wedge array situated upstream from the lens array in a radiation direction, the wedge array including a multitude of wedge elements, each of the wedge elements having a triangular cross section, a number of wedge elements equaling a number of the convex microlenses, each respective wedge element of the wedge elements being configured to receive radiation and to deflect the radiation onto the flat surface of a different respective convex microlens of the convex microlenses;
wherein the lens array has an optical axis, wherein each convex microlens of the lens array has a separate rotation angle, and wherein the rotation angles of the convex microlenses of the lens array that are a greater distance from the optical axis are greater than the rotation angles of the convex microlenses of the lens array that are at a smaller distance from the optical axis, wherein the rotation angle of each convex microlens is a rotation angle with respect to its respective wedge element.
