Embodiment Construction

[0074] figure 1 A device 1 for examining an eye is shown, which is formed as a slit lamp 1 . The slit lamp 1 comprises an illumination unit 100 , an optical component 220 and two objective lenses 240 mounted on a transverse slide 300 . The lateral slider 300 itself is mounted on a base plate 400, which can be formed as a table, and can move in X, Y, and Z directions. The slide 300 is controlled by means of an operator control unit 401 arranged thereon. Thus, the illumination unit 100 and the two objectives 240 are movable by means of the slide 300 and are also pivotably arranged independently of each other by means of the common axis of rotation 600 .

[0075] The lighting unit 100 for slit lighting comprises an L-shaped element 110 having a horizontal part 111 and a vertical part 112 . In the distal region of the horizontal portion 111 the L-shaped element 110 comprises a vertically arranged axis of rotation 600 . On top of the vertical section there is arranged a lightin...

Abstract

A device (1) for examining an eye, in particular a slit lamp, comprises an image recording unit (220) with at least one first sensor (241.1) in a first beam path and a second sensor (241.2) in a second beam path; the device also comprises in the first beam path a first objective with a first optical axis, which has a fixed magnification and is arranged as fixed in the first beam path.

Description

technical field [0001] The invention relates to a device for examining the eye, in particular a slit lamp, comprising an image recording unit with at least one first sensor in a first beam path and a second sensor in a second beam path. Two sensors. The invention also relates to a method for determining image data with an eye examination device. Background technique [0002] A slit lamp microscope is an ophthalmic examination device with which the eye can be examined monoscopically or stereoscopically. For stereoscopic viewing of the eye, known slit lamp microscopes have an optical unit for generating two images of the eye and two eyepieces for stereoscopic viewing of these images, and also an illumination unit. The lighting unit is arranged on a vertically extending branch of the holding unit. The eye to be observed can be positioned in a substantially horizontally extending plane on one side of the holding unit. The lighting unit comprises incandescent lamps, LEDs or s...
