  • Device for fine positioning of a component
    Patent number: 6311574
    Abstract: A device for fine positioning of a component (1), especially for vertical fine positioning of an objective or revolving objective nosepiece (1) of a microscope, with a lever system (3) and a drive (4) for the lever system, is characterized in that the lever system (3) acts directly on a rotating part (5); that the component (1) is flexibly connected to the rotating part (5); and that the connection (6) acts such that rotation of the rotating part (5) changes the position of component (1) by unrolling the flexible connection (6) on the rotating part (5), thus causing a lifting movement of the component (1).

  • Fine focusing table
    Patent number: 6137627
    Abstract: A fine-focusing stage for microscopes, with an object carrier (1) , a holder (2) for the object carrier (1) and a positioning mechanism (3) adjusting the support in its horizontal position. In order to achieve parallel vertical displacement of the object carrier (1) using simple methods of construction the invention is so designed that the holder (2) comprises a mounting portion (4) preferably for mounting on an object stage or on the microscope and a connecting portion (5) with the object carrier, and articulated parallel arms (8,9) through bending elements (6,7) extend between the mounting portion (4) and the connecting portion (5).

  • Device for feeding a UV laser into a confocal laser scanning microscope
    Patent number: 5903688
    Abstract: A device for feeding a light beam from a UV laser (1) into a laser scanning microscope (2) has a beam-alignment assembly (3) for aligning the laser beam with the beam path of the microscope (2) and an optical-fiber element (4) located between the UV laser (1) and the beam-alignment assembly (3). The aim of the invention is to design the feed device so that it can be used for long periods in order to keep the time and expense necessary to change the feed device as low as possible. To achieve this, the invention provides a beam interrupter (5) located between the UV laser (1) and the optical-fiber element (4). The beam interrupter allows the beam from the UV laser (1) to pass through the optical-fiber element (4) only during scanning, i.e., when pictures are being generated.
