Abstract

An optical projection device with a micro mirror is specified which accepts light from an angular range which has different acceptance angles (Φ 1, Φ 2) in two different directions. In this arrangement, the optical projection device allows the quantity of light provided by a light source to be utilized in a particularly efficient manner.
