The invention relates to a mount assembly comprising two monolithic mounts in which optical components (), which can be translationally and rotationally adjusted in relation to each other, are held. The adjustment movements can be carried out without influencing one another, by providing one of the mounts as a rotational mount () and the other as a translational mount (), which substantially only permit a translational and/or a rotational movement within the adjustment region provided.

Independently adjustable mount assembly for two optical components

A thermally compensated optical subassembly having a rotationally symmetrical optical element and a monolithic mount with a rotationally symmetrical mounting ring, having an axis of symmetry, and at least three connection units. The optical element communicates with the mounting ring via the connection units, so as to be secured against tilting and fixed with respect to torsion. 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.

The invention relates to an exposure device () for the structured exposure of a wafer, having at least one exposure arrangement with which a beam that is separated into two sub-beams is modulated via two micromirror arrays in order to increase the throughput speed during the exposure of wafers.

Adjustable mount assembly having two mount parts which are adjustable relative to one another and which themselves form adjustable mounts respectively comprising an outer mount frame and an inner mount frame. The mount assembly permits a highly precise adjustment of two optical components relative to one another in a plane perpendicular to an axis and an adjustment of the two mutually adjusted optical components relative to a reference base.

Mount assembly, which is adjustable in a plurality of steps, for two optical components

A device for the temperature-dependent axial movement of an optical component including a monolithic mounting unit having an outer mounting part forming a fixed holder having an axis and an inner mounting part forming a mount adapted to support the optical component. The mount is movable along the axis. A moving mechanism is connected to the fixed holder and the movable mount. The moving mechanism includes at least one external expansion element including a first material having a first coefficient of thermal expansion and at least one internal expansion element including a second material having a second coefficient of thermal expansion, where the first coefficient of thermal expansion is larger than the second coefficient of thermal expansion. A number of connecting links is disposed in a star-shaped formation and join a respective one of the at least one external expansion element to a respective one of the internal expansion element. Each connecting link is disposed at a prescribed pitch angle with respect to the axis that differs from 90&#xb0;.

The present invention relates to an optical mount, in particular a lens mount, which is divided by a plurality of cuts in the mount material into a stationary outer mounting ring, a laterally adjustable inner mounting ring and three bent lever manipulator units which are offset by 120&#xb0; relative to one another and which comprise a bent lever having a first element, one end of which is connected by way of a bent lever flexure hinge to one end of a second element, the other end of the first element being connected to the inner mounting ring, the other end of the second element being connected to the outer mounting ring, and with the first and second elements enclosing a bent angle smaller than 180&#xb0;. By manipulating the three bent lever manipulator units, any center position of the inner mounting ring can be adjusted relative to the center of the outer mounting ring within an intended displacement range.

The invention is directed to a tool head for machining of materials by laser, substantially comprising focusing optics which are arranged in a housing and through which a laser beam bundle is directed to the workpiece surface to be machined, a nozzle which coaxially surrounds the optical axis of the laser beam bundle and conducts gas in the beam direction in order to prevent contamination of the focusing optics by particles released on the workpiece surface to be machined, a pipe which coaxially surrounds the nozzle and which likewise conducts gas for preventing contamination of the nozzle, and a suction device with suction nozzles.

An apparatus is described for producing a three-dimensional object from a powder material which includes powder particles and which is solidifiable by exposure to electromagnetic radiation. The apparatus includes a support having a substantially plane support surface for supporting said object, an applying device for applying a layer of the powder material to the support surface, a radiation device for selectively exposing the powder material to electromagnetic radiation at places corresponding to the object and a discharge electrode for generating an electric field for reducing charge differences on the powder particles.
