Abstract

The fact that a beam-deflecting device can be produced cost-effectively and without any losses of optical quality of the multi-aperture imaging device is used when a carrier substrate is provided for the same, wherein the carrier substrate is common to the plurality of optical channels and is installed with a setting angle, i.e. oblique with respect to the image sensor in the multi-aperture imaging device such that a deflection angle of deflecting the optical path of each optical channel is based, on the one hand, on the setting angle and, on the other hand, on an individual inclination angle with respect to the carrier substrate of a reflecting facet of a surface of the beam-deflecting device facing the image sensor, the reflecting facet being allocated to the optical channel.
