Abstract
A system described herein includes a first lens, a first image stabilization unit and a first image plane. When seen from the first lens in the direction of the first image plane, the order in which the elements are arranged along a first optical axis is as follows: first lens, first image stabilization unit and first image plane. The first image stabilization unit has at least one first inlet surface and at least one first outlet surface. The first inlet surface is oriented towards the first lens. The first outlet surface is oriented towards the first image plane. Furthermore, the first outlet surface is spaced apart from the first image plane in a range of 1 mm to 20 mm.
