Abstract: A beam-forming and illuminating system for a lithography system, such an EUV lithography system, includes an optical element and an adjusting device. The adjusting device is configured so that, during a heat-up phase of the beam-forming and illuminating system, the adjusting device measures a field position and/or a pupil position of the beam-forming and illuminating system and adjusts the orientation and/or position of the optical element based on the measured field position and/or pupil position to keep the optical element in a desired position.

Abstract: A surgical microscope (100) has a viewing optic (101, 104, 115) which allows a viewing person to view the enlarged display of an object region (116) in a viewing area (117). The viewing optic (101, 104, 115) has a continuously adjustable magnification system (104) with which a viewing optic adjusting unit (119) is associated. The surgical microscope (100) has an adjustable illuminating system (150), which provides illuminating light (151) for the object region (116), to illuminate the object region in an illuminated area (152) using illuminating light (151) of adjustable radiation intensity. An illumination system control unit (175) is provided in the surgical microscope (100), the control unit being connected to the viewing optic adjusting unit (119) for receiving information as to the adjusted magnification of the viewing optic (101, 104, 115).

Abstract: A stand arrangement (100) for a medical-optical instrument includes a first link (104) which is pivotally journalled on a holding unit (101) with a first rotational joint. The stand arrangement further includes a second link (107) which is rotatably connected to the first link (104) via a second rotational joint (106). In a forward section (108) of the second link (106), a take-up unit (110) for medical-optical equipment (111) is held with a third rotational joint (109). The take-up unit (110) includes a front link (112) which is coupled to a device for force transmission (115). This device is rotatably journalled on the second rotational joint (106). In the stand arrangement (100), a device is provided for coupling the holding unit and the device for force transmission. This device for coupling includes a flexible force transmitting element (133) which can be loaded in tension.

Abstract: The invention relates to a stand arrangement (100) for a medical-optical instrument. The stand arrangement includes a first link (104) which is pivotally supported on a holding unit (101) by a first rotational joint. The stand arrangement (100) further includes a second link (106) which is rotatably connected to the first link (104) via a second rotational joint (105). A take-up unit (109) for medical-optical equipment is held in a forward section (107, 108) of the second link (106) by a third rotational joint. The take-up unit (109) includes a front link (111) which, in turn, is connected via a third link (112) and a fourth link (113) to the second rotational joint (105). The holding unit (101) and the fourth link (113) are coupled with the aid of a toothed gear unit (118) in such a manner that the orientation of the front link (111) does not change with the movement of the first link (104).
