Method and apparatus for adjustment and automatic readjustment of the lamp in a microscope
First Claim
1. Apparatus for the adjustment of the lamp in a microscope, comprising:
- a collector and a reflector which form a mechanical unit;
a lamp cap which is arranged between the collector and reflector for receiving the lamp; and
devices for the adjustment of the lamp and of the collector-reflector unit;
said lamp having a mark of the tilting direction of its glass body relative to the lamp cap;
said lamp cap having a mark for the 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;
said collector-reflector unit being displaceable for adjusting in direction of the optical axis; and
said lamp cap being displaceable for adjustment in a vertical direction.

Abstract
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. The proposed solution can be applied in all devices in which an ultra-high pressure gas discharge lamp is to be moved into and/or maintained in a focus position.

- 6. A method for the adjustment of the lamp in a microscope, wherein a lamp cap receiving the lamp is arranged between a collector and a reflector which form a mechanical unit, and the lamp cap and collector-reflector unit have devices for adjustment, wherein 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, the lamp cap is displaced in direction of the optical axis of the collector for adjusting the collector-reflector unit in order to orient the light arc generated between the electrodes of the lamp in the focal plane of the collector and subsequently, by displacing the lamp cap in vertical direction, on the optical axis of the collector.
