A device for varyingly irradiating by means of ray shaping is described. Furthermore, a method of manufacturing a structure made of a curable material by means of molding is described. In a first step of the method, a molding tool is arranged above a surface such that the curable material abuts on the surface and a molding surface, facing the surface, of the molding tool in a region between the molding tool and the surface and such that further curable material may continue to flow to the region. In a second step, the curable material is irradiated in the region in a locally varying manner such that the ray experiences ray shaping in an optical channel and such that the curable material cures at different speeds in a laterally varying manner.

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.

A multi-aperture imaging device described herein includes at least one image sensor and an array of juxtaposed optical channels. Each optical channel includes optics for projecting at least one partial area of an object area on an image sensor area of the image sensor. The array includes: a housing including a wall structure facing or facing away from the image sensor, through which the optical channels pass, and a sidewall structure arranged on the wall structure, wherein the wall structure or the sidewall structure is formed including glass, ceramic, glass ceramic or a crystalline material, wherein the optics of the optical channels are arranged in the housing, and wherein the wall structure is connected to optics of the optical channels and fixes the optics with respect to one another.

Multi-aperture imaging device includes at least one image sensor, an array of juxtaposed optical channels, wherein each optical channel has optics for projecting at least one partial area of an object area on an image sensor area of the image sensor, and a beam deflector for deflecting an optical path of the optical channels in beam-deflecting areas of the beam deflector. The beam deflector is formed as an array of facets arranged along a line-extension direction of the array of optical channels. One facet is allocated to each optical channel. Each facet has a beam-deflecting area. A stray light suppressing structure is arranged between a first beam-deflecting area of a first facet and a second beam-deflecting area of a juxtaposed second facet, which is configured to reduce transition of stray light between the first beam-deflecting area and the second beam-deflecting area.
