Abstract: A device by which the magnification stages of a magnification selector based on Galilean telescope systems can be adjusted by a motor. The magnification selector has a sensor that transmits the currently magnification stage to a control unit; in the control unit, an assignment of the magnification stages present on the magnification selector to a sequence of the magnification stages, organized based on size, is stored. For the user, there are operating elements connected to the control unit for selecting a magnification stage. In order to set the magnification stage selected by the user via the operating elements, the magnification selector has an actuator, which is connected to the control unit to receive appropriate control signals. Although provided in particular for slit lamps and surgical microscopes having eyepieces, the solution can also be applied in other ophthalmological devices or devices from other technical fields.

Abstract: An arrangement for adapting the focal plane of an optical system to a non-planar, in particular spherical or spheroidal object, wherein the optical system has a positive total refractive power and generates a real image. The optical system also comprises an optical element with a negative refractive power. Principally useful in all technical fields with the corresponding requirements relating to a curved focal plane, the arrangement is useful in ophthalmologic devices. The eye which is to be examined is the spherical or spheroidal object for example, the front of the eye which has radii of between 5 and 10 mm of small dimensions.

Abstract: A method for controlling the illumination of ophthalmological devices which operate in an observation mode and a recording mode. The method adapts the illuminance from ophthalmological devices which include an observation mode and a recording mode and the illuminance therefrom being increased above a specified value for the radiant flux ?soll for the duration of the recording mode. According to the invention, the illuminance is increased to a radiant flux above the specified value ?soll for the recording mode and lowered to a radiant flux below the specified value for the radiant flux ?soll for a specified period of time after the recording mode has finished. Although the proposed method for adapting the illuminance is provided for slit lamp microscopes, it can be used for any ophthalmological device that has both an observation mode and a recording mode to obtain high-quality, well-lit recordings in the recording mode.

Abstract: A fundus camera with an OCT measurement module, in which, after the focusing objective, a mirror switches the light to be detected either to the OCT measurement module or an image detector. This design also renders it possible to carry out a method for improved focusing in order to improve the recording quality of the individual modalities. Furthermore, the multimodal measuring instrument distinguishes itself by an operating concept according to the invention. Such combination instruments are advantageous in that, as a result of the reduction from two instruments to one, less space is required than in the case of two separate instruments. Furthermore, reseating of the patient is avoided if recordings or measurements of different modalities should be made for one and the same patient, as a result of which the procedures in the medical practices and clinics can be influenced positively.
