Publication number: 20150177594Abstract: An interchangeable camera lens includes a main barrel for holding a diaphragm and optical elements, wherein the optical elements define an optical axis (A), a diaphragm rotating ring, rotatable by way of a rotational movement about the optical axis (A), for setting the diaphragm to different f-number values, and a click-stop device. The click-stop device interacts with the diaphragm rotating ring in such a way that the click-stop device is effective in an active work position and the diaphragm rotating ring is therefore rotatable in a stepped manner. The click-stop device is ineffective in an inactive work position and the diaphragm rotating ring is therefore continuously rotatable, wherein the click-stop device comprises a click-stop element seated on a pressure element. The click-stop element is pressable into click-stop grooves by the pressure of the pressure element to enable a step-wise rotation of the diaphragm rotating ring in the active work position.Type: ApplicationFiled: December 19, 2014Publication date: June 25, 2015Inventor: Uwe Weber

Patent number: 6784441Abstract: A manually controlled sensor for authenticity identification of luminescent identification features on documents is described, in which the identification feature is illuminated with an excitation wavelength and may respond at a different wavelength, with the response wavelength being detected and evaluated by a radiation receiver. In order to improve the sensitivity and to comply with the safety at work regulations, a focused beam (31, 32), which is emitted from a beam source (1), is converted by focusing optics (2, 3) in such a manner that a scanning bar (22), which is approximately in the form of a line, is projected on the surface of the object (5) to be investigated, which causes the identification region (21) which is arranged on the object (5) to fluoresce in a luminescent manner in at least one subregion, and the luminescence signal produced in this way is passed via detection optics (9, 9′, 10) to an evaluation unit (11), which evaluates the luminescence signal.Type: GrantFiled: July 3, 2001Date of Patent: August 31, 2004Assignees: Bundesdruckerei GmbH, Baumer Electric AGInventors: Benedikt Ahlers, Roland Gutmann, Arnim Franz-Burgholz, Anett Bailleu, Manfred Paeschke, Peter Halter, Hans Zerbel, Uwe Weber
