摘要： A binocular stereoscopic viewing device for examining an eye having a light source and a first light guide for directing light from the light source to the eye to be illuminated. A second light guide redirects light representing the stereoscopic image of the eye. A support mechanism supports both the first light guide and second light guide and is operable for moving in directions towards and away from the eye. A tilting mechanism repositions the first light guide relative to the second light guide for varying the angle at which light from the light source is directed by the first light guide toward the eye to be illuminated.

摘要： A stereoscopic ophthalmoscope for examining an eye including two inner reflection mirrors for guiding light representing the image of the eye toward a pair of external mirrors. Each of the external mirrors serves as an image splitter for dividing the light into two distinct optical observation paths. The first optical observation path is used to produce a stereoscopic image of the eye suitable for binocular viewing. The second optical observation path is used to produce a non-stereoscopic image of the eye suitable for monocular or binocular viewing.

摘要： A magnifier for observing a surface includes a housing, a detachable window attachment coupled to a first end of the housing and an eyepiece coupled to a second end of the housing. A light source attachment is coupled to the housing for supplying light to the hollow interior of the housing. The light source attachment and housing each have major axes which extend in different directions and form an angle between approximately 110.degree. and 120.degree.. Photoconductive material serves as a light guide for directing the light from the light source attachment to the window attachment.

摘要： A binocular indirect ophthalmoscope is disclosed in which the optical observation axes from the examiner's pupils to the patient's pupil and the optical illumination axis from an illumination source to the patient's pupil are varied simultaneously by a single conveniently located lever. Mirrors reflecting the observation axes and the illumination axis are mounted on a common movable holder in fixed relationship to each other. The lever is coupled to the holder to move the holder in the observation plane upon actuation of the lever and thereby adjust both the observation axes and the illumination axis at the same time.

摘要： Head-worn apparatus to which an optical device is adjustably coupled is disclosed. The apparatus comprises a headband, a support bow for the optical device rotatably coupled to the headband and a locking mechanism for automatically locking the bow in a viewing position of the optical device and in a rest position of the optical device while permitting the bow to be swivelled between the two positions. An articulated coupling adjustably connects the optical device to the central region of the bow. The locking mechanism always locks the bow in the same viewing position of the optical device so that once the articulated coupling has been adjusted with the optical device in its viewing position, the bow and with it the optical device can be swivelled back and forth between the rest and use positions without having to readjust the optical device. This arrangement enables a user to position an optical device in front of his or her eyes for use and move it out of the way without either taking the apparatus off his or her head or readjusting the optical unit.
