Abstract: Lighting arrangement for a diagnostic or surgical microscope has a light source, and the lighting arrangement defining an illuminating beam path. An illumination optics is arranged between the light source and an objective of the microscope which defines an imaging beam path, and in the beam path of the light source at least one deflection element is arranged for coupling in of the illuminating beam path into the imaging beam path. The illumination optics has at least one pancratic system. The lighting arrangement has, in the manner of a Köhler illumination, a collector lens arrangement which is arranged downstream of the light source in the beam direction of the light source, a field diaphragm arranged downstream of the collector lens arrangement, and an auxiliary lens arrangement arranged downstream of the field diaphragm, and the auxiliary lens arrangement has at least one pancratic system.

Abstract: A deep-drawn inner coating or an inner door of a cooling equipment. An insertion element is maintained by form-closure in a recess of a wall. In order to facilitate the accurate fixing of the position of a component incorporated in the insertion element, the insertion element extends at least up to a plane flush with a surface of the wall surrounding the recess.

Abstract: The invention relates to an irradiation unit for the UV irradiation of particularly web-shaped substrates, comprising a housing (10), a tubular UV lamp (12), arranged therein and a reflector arrangement (14), running along the UV lamp (12). According to the invention, a simple exchangeability may be achieved, whereby the reflector arrangement comprises a support profile (22), retained in the housing (10) and a reflector profile (24), embodied as a shape-retaining molded piece which may be detachably connected thereto.

Abstract: A method is provided for producing a refrigeration device with a refrigerated interior that is delimited by an inner shell. The refrigeration device includes a space between the inner shell and an outer shell into which a curable insulating foam is injected. A sealing material is injected into the space before the injection of the insulating foam, the sealing material sealing joints or gaps and preventing the passage of the insulating foam through the joints or gaps.

Abstract: The invention relates to a UV irradiation unit comprising a housing (10), a rod-shaped lamp (12) which is arranged therein, a reflector (14) which extends along the UV-lamp (12) and which defines a lamp chamber (22) which surrounds the UV-lamp (12), in addition to a channel system (20) for guiding a cooling coolant through the reflector (14). According to the invention, the channel system (20) is arranged on the outside of the lamp chamber (22) such that it remains void of the coolant flow (24) for operating the lamp in an optimum manner.
