A fundus camera for the recording of high-resolution color images of the fundus of non-dark-adapted eyes, and without the use of a mydriatic. The fundus camera has a strip-shaped pupil division, and includes a coherent or incoherent illumination source with illumination optics, a deflection mirror and an ophthalmoscope lens for illuminating the eye, detection optics and a detector for detecting the light reflected by the eye, and a control and evaluation unit. The deflection mirror has a strip shape, and the spatially resolving detector can be activated and read out in sectors. The control and evaluation unit connects the data read out in sectors in the form of a bright image from the detector and produce a resulting fundus image. The fundus camera records images of the fundus when the eyes are not dark-adapted for this purpose and no mydriatic has been used.

Fundus camera with strip-shaped pupil division, and method for recording artifact-free, high-resolution fundus images

An ophthalmic device and an arrangement for generating images with expanded dynamic range and a corresponding method for generating images with expanded dynamic range have at least one beamsplitter, in particular with an asymmetric splitting ratio, and at least two image sensors, wherein the image sensors are reflected into a common imaging beam path by the at least one beamsplitter.

Arrangement and method for generating images with expanded dynamics

The invention relates to a device for observing the ocular fundus, in particular to a fundus camera. Said device comprises a light source () for the provision of illumination radiation, an illumination optical path for directing the illumination radiation onto the ocular fundus and observation optics for reproducing the illuminated ocular fundus, the observation optics comprising a module (), whose refractive power can be electrically adjusted.

Focusing and astigmatism compensation device for a fundus camera

An ophthalmological examination device, especially a slit lamp or a fundus camera, for observing a patient's eye, with at least one image recording unit such as a video camera or a CCD-chip for recording at least a part of the image of the eye generated by the examination device, and with a device for transmitting the electric signals of the video camera or CCD-chip to an image generating unit connected with the head of the observer. In an advantageous manner, it is possible to superimpose on a first image generated from the electric signals of an image recording unit additional information generated by a computer via the image generating unit, at least for one eye of the observer, and/or to display a second image to the observer, which second image is modified with respect to color, contrast or other image features, as an additional image superimposed on the other respective eye or on the first image for one or both eyes of the observer. The additional information comprises stored images and/or stored previous recordings and/or physiological data on the patient.
