Abstract
An optical element is configured by connecting a plurality of tiles each constituted by a plurality of reflective optical elements, and is formed in a shape having a plane surface. The tiles configuring the optical element are formed such that outer shapes on the plane surface of the tiles have at least two different triangular shapes, while an end surface of each tile is provided with a light shielding part.

- each of the tiles includes an upper tile and a lower tile layered in a direction perpendicular to the plane surface,
- the reflective optical elements in the upper tile correspond to a plurality of mirrors extending in one direction, and
- the reflective optical elements in the lower tile correspond to a plurality of mirrors extending in a direction orthogonal to the one direction.
An optical element including a plurality of tiles each constituted by a plurality of reflective optical elements and having a plane surface, wherein,
- outer shapes on the plane surface of the tiles have at least two different geometric shapes and the tiles are arranged non-periodically on the plane surface, and
- an end surface of each of the tiles is provided with a light shielding part,
- each of the tiles includes an upper tile and a lower tile layered in a direction perpendicular to the plane surface,
