Patent number: 7045984Abstract: Method and apparatus for the adjustment and automatic readjustment of the lamp in a microscope. The present invention is used for adjusting the lamp in a microscope. In the solution according to the invention, the tilting direction of the glass body relative to the lamp cap is marked at the lamp. The lamp cap is likewise marked for oriented insertion of the marked lamp so that the tilting direction of the lamp lies in direction of the optical axis of the collector after insertion. For adjusting, the collector-reflector unit is displaced in direction of the optical axis of the collector and the lamp cap is then oriented in vertical direction of the optical axis of the collector. For automatic readjustment, the lamp cap has an actuating drive. A reference variable is determined for the actuating drive by a control unit by evaluating lamp voltage or lamp current.Type: GrantFiled: September 24, 2004Date of Patent: May 16, 2006Assignee: Carl Zeiss Jena GmbHInventor: Matthias Gonschor
