Abstract: An interferometer device includes an interferometer unit with at least two mirrors disposed in parallel, wherein at least one of the mirrors is actuatable parallel to the other mirror and a first distance between the two mirrors is alterable. The interferometer device further includes at least one deflection mirror disposed downstream of the interferometer unit in a light transmission direction of light from the interferometer unit and a detector device, onto which the light is able to be aligned by the deflection mirror. The detector device includes at least two differently sensitive detection regions for transmitted wavelengths or wavelength ranges of the light, which detection regions are spatially separated from one another and able to be irradiated separately by the deflection mirror.

Abstract: A micromechanical mirror device, a mirror system, and a method for producing a micromechanical mirror device are disclosed. The mirror device comprises a first mirror element, which is flat, and a second mirror element, which is flat. The first and second mirror elements are arranged substantially plane-parallel. An intermediate space between the first and second mirror elements has a lower index of refraction than one or both of the first mirror element and second mirror element. The first and second mirror elements are locally spaced apart from each other by at least one support structure. The support structure overlaps with the first and second mirror elements in an axial direction, which is perpendicular to the first and second mirror elements. The support structure includes a material that is different from a material from which one or both of the first and second mirror elements are formed.

Abstract: A spectrometer device includes an optical interference filter which is designed to filter specific wavelength ranges of an incident light beam on passage through the optical interference filter. The spectrometer device also includes a detector device which is designed to detect the filtered light beam. Further, the spectrometer device includes a focusing device with a reflective surface. The focusing device is designed to focus the filtered light beam onto the detector device by reflection on the surface.

Abstract: The disclosure relates to a mirror device for an interferometer device including a first mirror layer and a second mirror layer, which are arranged in parallel on top of one another and spaced apart from one another by a mirror layer spacing. The mirror layer spacing forms an intermediate space between the first and the second mirror layer. The intermediate space includes a gas or a vacuum, and at least one spacing structure which extends at least partially between the first and the second mirror layer. The spacing structure has a material that is the same as or different from the first and/or second mirror layer.

Abstract: An interferometer includes a holding element having an actuation recess, a first mirror element arranged on the holding element opposite the actuation recess, and a second mirror element arranged opposite the first mirror element at a mirror distance, to form an optical slit. The first mirror element is arranged between the second mirror element and the holding element and the optical slit is spatially separated from the actuation recess by the first mirror element. The interferometer further includes an electrode pair including a first actuation electrode in one of the mirror elements and a second actuation electrode on a side of the actuation recess opposite the first actuation electrode. The mirror distance can be varied by applying an electrical voltage to the electrode pair.
