Use is made of the fact that a beam deflection device can be manufactured cost-effectively and without a reduction in optical quality of the multi-aperture imaging device if a common carrier substrate is provided for the multiple optical channels for said multi-aperture imaging device, which common carrier substrate is installed at an attitude angle, that is to say obliquely, with respect to the image sensor in the multi-aperture imaging device in such a way that a deflection angle of the deflection of the beam path of each optical channel is based, on the one hand, on the attitude angle and, on the other hand, on an individual inclination angle of a reflective facet, assigned to the optical channel, of a surface, facing the image sensor, of the beam deflection device with respect to the carrier substrate.
