Abstract: An optical arrangement with a light source includes an optical element that is fastened in a mount. The light source emits radiation and the optical element is acted on thereby such that the heat that results lacks symmetry corresponding to the shape of the optical element. A connecting structure is provided between the optical element and the mount and has a symmetry that does not correspond to the shape of the optical element and effects an at least partial homogenization of the temperature distribution in the optical element.

Abstract: An arrangement for holding a particle beam apparatus such as a transmission electron microscope. The arrangement is sufficient for receiving a good resolution in the area of 1 ? or less, said arrangement still being under more or less no influence of the environment, in particular, building vibrations. In one embodiment, the arrangement comprises a base structure comprising a plurality of hollow bodies, at least one of said hollow bodies having a first length extension in a first direction, a second length extension in a second direction and a third length extension in a third direction, said first length extension being larger than said second and third length extensions, and wherein a cross section of said at least one of said hollow bodies perpendicular to said first direction is substantially triangular. Due to the hollow body shape, a very stiff structure is provided with a very good eigenfrequency.

Abstract: The invention relates to a camera system, especially for photogrammetric applications. The camera system contains at least two first cameras (1, 2), which are inclined towards each other so that the optical axes (7, 8) of the first cameras (1, 2) intersect at a common point of intersection (5). The camera system also has at least two second cameras (10, 11) which are located at a distance from the first cameras (1, 2), in the viewing direction of the first cameras (1, 2). The inclination of the optical axes (7, 8) of the first cameras (1, 2) towards each other provides an area (b) in which the envelope that surrounds the acceptance cones of the first cameras (1, 2) has an essentially constant diameter. The second cameras (10, 11) are located in this area (b) so that the second cameras (10, 11) avoid truncating the projection of the visual fields of the first cameras (1, 2). The first cameras are preferably panchromatic and the second cameras polychromatic.

Abstract: The invention relates to a composite body which is assembled from at least two bodies. The first body is made of a first material and the second body of a second material and each of the two bodies has at least one joining surface. The joining surfaces lie opposite each other and the bodies are joined to each other by at least one adhesive connection. At least one recess for a compensating body made of a third material is introduced into at least one of the two joining surfaces. This compensating body is connected with at least one adhesive location or gluing gap to both bodies. An adhesive ensures an adhesive connection between the compensating body and the two bodies at the adhesive location.
