  • Publication number: 20170219811
    Abstract: The invention relates to a method for illuminating an object in a digital light microscope, to a digital light microscope, and to a bright field reflected-light illumination device for a digital light microscope. According to the invention, the bright field reflected-light illumination and the dark field reflected-light illumination are configured with light-emitting diodes as light sources and are individually or jointly drivable via a control unit. Both the bright field reflected-light illumination and the dark field reflected-light illumination are configured as “critical” illumination, in which the light source is imaged into the object plane.

  • Patent number: 9547164
    Abstract: A digital microscope system, having one or several objectives, a tube lens system, a digital image recording device, a stand, a holder for a specimen and an illuminating apparatus, and optionally at least one magnification changer. One or several objectives, the tube lens system, the digital image recording device and the illuminating apparatus are integrated into a compact optical assembly, and the optical assembly is joinable to the stand in several versions that differ with regard to the spatial position and orientation of the optical assembly relative to the stand and to the specimen. The spatial position and orientation of the optical assembly relative to the stand and to the specimen may correspond, in a first version of the joining, to an upright microscope configuration and, in a second version of the joining, to an inverted microscope configuration.

This changing device is arranged at a holder in the telecentric part of the microscope beam path and is outfitted with a quantity of optical components influencing the beam path. The arrangement is mounted so as to be rotatable around an axis of rotation which is situated in the holder and which intersects the optical axis of the microscope beam path. This axis of rotation defines, with the optical axis, a plane extending substantially perpendicular to the front wall of the microscope stand. The part of the changing device which is not located in the microscope beam path and which lies diametrically opposite to the part of the changing device that is located in the beam path is arranged so as to be directed toward the microscope stand and is adjacent to the front wall of the microscope stand.

  • Publication number: 20070146872
    Abstract: An optical microscope can be converted by the user quickly with a few movements of the hand so that it can be used as an upright variant or as an inverted variant. The required optical elements are accommodated in components that can be mechanically separated from one another and variously combined. The optical system is calculated in such a way that an upright microscope with vertical illumination or transmitted illumination or an inverted microscope with vertical illumination or transmitted illumination results when the components are combined in the required manner by interfaces provided for this purpose.

  • Publication number: 20050185274
    Abstract: A method for generating a stereoscopic image of an object includes providing a microscope arrangement defining an imaging beam path coming from the object. The microscope arrangement includes an objective mounted in the beam path to define an intermediate image plane. A reflective element is placed in or close to the intermediate image plane or in or close to a plane conjugated to the intermediate image plane. The reflective element is driven at a clock frequency so as to reflect respective images of the object alternately toward the left and right eyes of an observer.

  • Patent number: 6882473
    Abstract: An arrangement for generating a stereoscopic image of an object for viewing by an observer includes an imaging optic for imaging the object and defining an imaging beam path as well as an entry pupil and an exit pupil. Illuminating optics illuminate the object by providing an imaging beam coming from the object and passing through the imaging optic and along the imaging beam path. The imaging beam is sectioned in the imaging beam path into two component beams at one of the following locations: in the exit pupil, near the exit pupil or at a position along the imaging beam path which is optically conjugated to the exit pupil, thereby forming stereoscopic sectioned images. The stereoscopic section images are allocated in a clocked manner to the left and the right eyes of the observer. The invention is also directed to a method of generating a stereoscopic image of the object.

  • Patent number: 5835264
    Abstract: The invention is directed to a method and arrangement for generating stereoscopic images of an object. The method includes the steps of illuminating an object with an illuminating beam; masking the illuminating beam to generate a first component beam to illuminate the object at a first angle and provide a first image of the object to a first viewing eye; again masking the illuminating beam to generate a second component beam to illuminate the object at a second angle and to provide a second image of the object to a second viewing eye; and, alternately repeating the last two steps at a frequency above the flicker frequency of the human eye. In the arrangement of the invention, a beam generating device alternately generates first and second illuminating beam components which illuminate the object via illuminating optics at respectively different angles to produce respective images of the object.
