Abstract: Optical component (8) having a temperature dependent focal length comprising: a first rigid optical element (9) with a first interface (10); a second rigid optical element (11) with a second interface (12); a third optical element (13) comprising a third material, wherein the third optical element (13) is arranged between the first rigid optical element (9) and the second rigid optical element (11) such that the first interface (10) and the second interface (12) each face the third optical element (13); the third optical element (13) having a larger temperature coefficient of index of refraction than first rigid optical element (9) or the second rigid optical element (11); the first interface (10) and/or the second interface (12) being non-flat and configured to change an optical refraction power of the first interface (10) or to change an optical refraction power of the second interface (12) with changing temperature, wherein this change corresponds to the temperature dependent focal length of the optical

Abstract: The invention relates to an imaging optical system (1) comprising a folding component (2) and a tunable optical component (3) that are arranged on an optical path of the optical system (1), wherein the tunable optical component (3) comprises a first optical surface (7), a second optical surface (8) and a deformable internal space (9) between the first optical surface (7) and the second optical surface (8), which internal space (9) is filled with a transparent liquid (11), wherein an optical property of the tunable optical component (3) is adjustable by altering a shape of the internal space (9).

Abstract: The present disclosure describes proximity sensor modules that include a time-of-flight (TOF) sensor. The module can include a plurality of chambers corresponding, respectively, to a light emission channel and a light detection channel. The channels can be optically separated from one another such that light from a light emitter element in the light emission chamber does not impinge directly on light sensitive elements of the TOF sensor in the light detection chamber. To achieve a module with a relatively small footprint, some parts of the TOF sensor can be located within the light emission chamber.

Abstract: Light emitting modules, such as flash modules, include features to help reduce the visual impact of interior components and shield them from view. The features also may enhance the outer appearance of the module or of an appliance incorporating the module.
