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 ref ractive 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.

An adjustable mirror assembly comprising a mirror, a support, a leaf spring element biased between the support and a planar reverse side of the mirror, said leaf spring element generating a spring force, as well as at least two adjusting units mounted in the support and acting on the mirror in opposition to the spring force. The leaf spring element is mounted to the reverse side of the mirror via at least one mirror mounting point by a substance-to-substance bond and to the support via at least one support mounting point. The spring force is directed toward the support.

A device for variably influencing the wavefront of a beam, said device comprising a reflecting or transmitting planar optical element () and an actuating and holding means () which is connected to the planar optical element () via at least three elastic retaining lugs () such that forces can be introduced into at least one of the retaining lugs () via at least one actuating element () arranged in the actuating and holding means (), which forces are deflected in their direction of action by the bending of the retaining lugs () such that they cause forces on the peripheral surface () of the planar optical element () whose direction of action (R) is parallel to the axis of symmetry (A) of the planar optical element (), allowing the planar optical element () to be actively deformed.

The crown-like adjusting element () has crown spikes which act on retaining lugs () connected to the planar mirror () and deform them, thereby applying forces corresponding to said deformation into the planar mirror () in order to deform the latter.

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.

Stiffened lens mount

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&#xb0; 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.

The connection units, in each instance, have three couplers which have a determined length ratio with respect to one another and are connected to one another and to the mounting ring and optical element such that defined conditions are met.
