Abstract:
A lens mount with a mount ring (1) having a mount ring axis (1.1), at which mount ring (1) is provided an edge support (1.2) which is radially extended with respect to the mount ring axis (1.1), with a round optical component (2) which contacts the edge support (1.2) by an end face and with an intermediate ring (3) which contacts the other end face of the optical component (2) and which is fixed in position opposite the mount ring (1), e.g., by means of a screw ring (4.1). Three point-shaped first protuberances (1.3) and second protuberances (3.3), respectively, are provided at the edge support (1.2) and at the intermediate ring (3) in each instance on an imaginary circular ring (1.4) of identical size at angular distances relative to one another, and one each of the first protuberances (1.3) and one each of the second protuberances (3.3) lie in each instance on an imaginary straight line (5) running parallel to the mount ring axis (1.1) through the edge region (2.2).

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.

Abstract:
Thermally compensated mounting assembly with a monolithic mounting element and with a rotationally symmetrical element mounted therein, wherein the mounting element is divided into a mounting ring with an axis of symmetry and a plurality of elastic connection arms via which the mounted element is held in the mounting element. The connection arms have at least one portion which extends in axial direction of the axis of symmetry. A compensation ring contacts all of the connection arms inside these portions coaxial to the mounting ring. The compensation ring is advantageously made from the same material as the mounted element and completely absorbs the restoring forces occurring as a result of the temperature-dependent deformation of the connection arms due to a different expansion of the mounting element and of the mounted element so that invariant forces act on the connection points between the connection arms and the mounted element.
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.
Abstract:
Thermally compensated optical assembly comprising a monolithic mount which is divided by slits into a mounting ring and at least three elastic links which are connected to an optical element. The elastic links compensate the thermal expansion differences between the mounting ring and the optical element through deformation. The temperature-dependent reaction forces brought about by the deformation are compensated. For this purpose, the quantity of compensation elements is equal to the quantity of links. The compensation elements comprise in each instance an expansion body and a spring element.

A device for variably influencing the wavefront of a beam, said device comprising a reflecting or transmitting planar optical element (1) and an actuating and holding means (2) which is connected to the planar optical element (1) via at least three elastic retaining lugs (2.3) such that forces can be introduced into at least one of the retaining lugs (2.3) via at least one actuating element (2.4) arranged in the actuating and holding means (2), which forces are deflected in their direction of action by the bending of the retaining lugs (2.3) such that they cause forces on the peripheral surface (1.3) of the planar optical element (1) whose direction of action (RA) is parallel to the axis of symmetry (A) of the planar optical element (1), allowing the planar optical element (1) to be actively deformed.

The invention relates to a device with a planar mirror (1), comprising a first axis of symmetry (A), and an actuating and holding means (10) with a frame (2), said frame (2) being firmly connected to the peripheral surface (1.3) of the planar mirror (1) and centrally contacting the rear surface (1.2) of the planar mirror (1). There is a socket (3), which is linearly adjustable along the axis of symmetry (A) in the frame (2) and is firmly connected, via a membrane spring (8), to the frame (2), on the one hand, and to a crown-like adjusting element (5), on the other hand. The crown-like adjusting element (5) has crown spikes which act on retaining lugs (6) connected to the planar mirror (1) and deform them, thereby applying forces corresponding to said deformation into the planar mirror (1) in order to deform the latter.
