A guide component for joint guidance of at least two optical elements that are movable in relation to one another is described. The guide component comprises at least two separate planar sliding guide surfaces arranged with a fixed spatial alignment relative to one another, a first sliding guide surface comprising a first surface normal and being configured to rest against and slidingly guide a first optical element in relation to a second optical element, and a second sliding guide surface comprising a second surface normal and being configured to rest against and slidingly guide the second optical element in relation to the first optical element, the first surface normal and the second surface normal running parallel to one another in opposite directions.

Joint guiding of movable optical elements

The present invention relates to a spectrometer for spectral analysis of electromagnetic radiation. The spectrometer comprises an entry slit for entry of the electromagnetic radiation to be analysed and an imaging grating for diffraction of the electromagnetic radiation which has entered. The spectrometer additionally comprises a detector extending at least in one direction to detect the diffracted electromagnetic radiation, and also a support plate in which the entry slit is located. The spectrometer further comprises a housing which is mounted on the support plate, covers the detector and the entry slit and supports the imaging grating. According to the invention the spectrometer further comprises at least three floating bearings for floating mounting of the housing on the support plate, the floating bearings each enabling a displacement between the housing and the support plate on a directional axis and being distributed about a central axis of the housing.

An optical assembly having at least a first optical element and a second optical element, both of which are arranged to be movable in a guided manner, is provided. A guide common to both optical elements is present, which provides a guide path that is common to both optical elements during the guided movement of the first optical element and during the guided movement of the second optical element.

A long-range optical device has at least one optical channel which comprises a housing and an arrangement of optical elements. At least one of the optical elements is movable relative to the housing for image stabilization in the event of perturbing movements of the housing. The device further comprises a stabilization system for the at least one movable optical element, which has an eddy current damper for damping movements of the at least one movable element. The stabilization system, in the event of a displacement of the at least one movable optical element, generates a restoring force proportional to the displacement velocity of the at least one movable optical element. The eddy current damper comprises a magnet system and an eddy current carrier interacting therewith. The restoring force generated by the eddy current damper is dependent on the amplitude of the displacement of the at least one movable optical element.

Image-stabilized long-range optical device

A long-range optical device has at least one optical channel, which has a housing and an arrangement of optical elements, wherein at least one of the optical elements is movable relative to the housing for image stabilization in the event of perturbing movements of the housing. The device further has a first passive stabilization system based on mass inertia for the at least one movable optical element, which, in the event of displacement of the at least one optical element relative to the housing, generates a first restoring force proportional to the displacement and a second restoring force proportional to the displacement velocity. The first stabilization system is designed for image stabilization in the event of perturbing movements in a first frequency range. The long-range optical device has at least one second stabilization system, which is coupled to the first stabilization system and is designed for image stabilization against perturbing movements in at least one second frequency range, wherein the first and the at least one second frequency ranges are at least partially different.
