Abstract: A stiffened lens mount with an outer mount ring having an axis of symmetry, an inner mount ring arranged coaxial to the outer mount ring and connection structures. The inner mount ring has at least one end face arranged perpendicular to the axis of symmetry, and a coaxially arranged stiffening ring fixedly connected to the inner mount ring via the at least one end face along an imaginary circle.

Abstract: The invention relates to a device comprising a beam splitter and a method of using the device. The device comprises a beam emitting unit and a downstream beam splitter, which is formed by two adjacent planar plates of different materials. For a specified wavelength range of an optical beam from which a partial beam is to be coupled out by reflection, the material of the first planar plate has a minimum refractive index which is greater by a refractive index interval than the maximum refractive index of the material of the second planar plate. From the optical beam, which, collimated and linearly polarized parallel to a plane of incidence, impinges on the beam splitter at a certain angle of incidence, the partial beam having only a small summary percentage of the optical beam and a small spectral fluctuation range is coupled out.

Abstract: A monolithic lens mount is formed by an annular body which is divided through material recesses into an outer mount ring, an inner mount ring and three connection structures which are arranged so as to be offset by 120° relative to one another. The connection structures in each instance form a chain of at least three, preferably five, connection webs which transition into one another and which are constructed as radial connection webs and axial connection webs. The axial flexural stiffness and radial flexural stiffness and the torsional stiffness of the connection structures can be determined via the dimensioning of the radial connection webs and axial connection webs.
