    摘要: The invention contemplates an improved ophthalmological instrument wherein photo slit-lamp function (for anterior-chamber examination of an eye) are combined with fundus-camera functions (for posterior-chamber examination of the eye), with important advantages of manipulating convenience and reduced cost. The invention is disclosed (a) for the case of a photo slit-lamp accessory for use with an existing fundus camera and (b) for the case of a more compact new instrument to serve both functions.

    摘要: An ophthalmological instrument having optical elements providing an examination light beam path and an illumination light beam path. The optical elements include an objective for producing an inverted magnified flattened image of the fundus of the eye, and further elements for focusing this image at infinity and projecting it selectively either into an observation tube or into a camera or other documentation device where a record of the image may be made. The illumination beam path includes a source of light and means of projecting this light, via a perforated mirror, into the pupil of the patient.

    摘要: An ophthalmological instrument for stereoscopic examination of the fundus or retina of the eye of a patient, and documentation thereof, as by photographing it. The instrument provides an observation light beam path, and an illumination light beam path. In the observation beam path are various optical elements for producing an image of the fundus at appropriate places, and a beam splitter to split the beam into two parts for stereoscopic viewing. A movable deflector can be shifted to a position to deflect at least part of the beam to a camera or other documentation device.

    摘要: A device for the remote control of motions and operations, especially on microsurgical equipment, comprises a multiple switch assembly in which the operation of the selected switches is controlled by movement of a control member. Operation of the switches closes or opens electrical circuits which include servo-mechanisms for moving the equipment. The switches are mounted in a housing and the control member comprises a plate having a stud extending through an aperture in the cover of the housing. Selective operation of the switches is brought about by transverse movement of the plate and stud in various directions.

    摘要: An illuminating device for a stereo microscope having an objective with variable imaging focal intercept includes first coupling mechanism, which effects a coupling between the imaging focal intercept of the objective and the likewise adjustable focal intercept of the illuminating optical system, separate from the observation optics, in such a manner that the illuminating focal intercept is in agreement with the imaging focal intercept of the objective. Moreover, adjusting mechanism is provided for the defined adjustment of the diameter of the illuminated field. In particular, the illuminating device is suitable for a surgical microscope.
