  • Publication number: 20130175412
    Abstract: A stand (10, 100) for holding a medical device (W1, W2, W3) includes a stand foot (9) and a carrier unit (1) connected to the stand foot rotatably about an axis (S), the medical device being mountable on the carrier unit. The stand also includes a counterweight (W4) to compensate for the torque about the axis produced by the medical device and the carrier unit, a first receiving unit (6, 102) at a first location for receiving at least a portion of the counterweight, and a second receiving unit (7, 104) at a second location for receiving at least another portion of the counterweight. Upon a change in torque about the axis, a proportion of the counterweight received by the first receiving unit is increasable by a compensation value, and that proportion of the counterweight which is received by the second receiving unit is reducible by that compensation value.

  • Publication number: 20130140411
    Abstract: The invention relates to a stand, in particular to a stand for a surgical microscope, having a pivotable carrier arm (4) and having a microscope holder (6) pivotable in a plane at the distal end of the carrier arm (4), the angular position (21; 24) of the microscope holder (6) being definable with reference to the carrier arm (4), and having a motorized drive that engages on the one hand on the carrier arm and on the other hand on the microscope holder (6), and in the context of operation defines the angular position (21; 24) in remotely controlled fashion and/or automatically. This construction eliminates complex parallelogram supports and angle transfer elements that link the tilt of the microscope holder (6) depending on the pivot position of the carrier arm (4). The construction thus becomes simpler and lighter, and less dependent on production tolerances.

  • Publication number: 20130070076
    Abstract: A method and device for autofocusing in a microscope (11), wherein two preferably spot-shaped, markers (12) are generated on an object, the spacing (d) of the markers representing an indication of the defocusing of a working plane (9) in the object from the focal plane (10) of the microscope (11). A focus drive (6) displaces the working plane (9) into the focal plane (10) as a function of the marker spacing (d). In order to allow rapid and exact focusing to be performed, a detector (4) acquires an image of the markers (12) generated on the object, an evaluation unit (7a) determines the spacing of the markers (12), and a control unit (7b) adjusts, as a function of the determined marker spacing (d), the speed of the focus drive (6) at which the working plane (9) is displaced into the focal plane (10).

  • Publication number: 20130070335
    Abstract: A microscope includes a light source including an LED device having a light radiating surface and a light directing element including a larger coupling-out surface. The light directing element is disposed so as to couple in light radiated by the light source and couple out the radiated light from the coupling-out surface. The light directing element is disposed so that the light is radiated out in an angular range of ±10° to ±50° and illuminates an area at 5 meters in an angular range of at least ±5° with intensity fluctuations of less than 50%. A condenser is disposed between the coupling-out surface of the light directing element and the object to be viewed. The condenser has an aperture with an aperture dimension and is disposed such that the aperture is irradiated completely with the light coupled out from the coupling-out surface.
