The invention relates to a slit projector comprising a light source, a slit diaphragm arranged in front of the light source, and a lens system arranged in front of the slit diaphragm. Such a slit projector is used in particular in slit lamps. The front chamber of the eye can be illuminated with such slit projectors in order to be able, for example, to take pictures of the slit image of the front chamber of the eye. High performance light sources are needed for this. These are presently not available at acceptable prices. Therefore, the purpose exists to improve a slit projector in such a manner that same presents a slit of the needed brightness for viewing the eye and in particular for slit image photography. This is attained in such a manner that the light source consists of several light diodes arranged essentially in a longitudinal direction of the slit, namely in the plane of the projected slit.

Slit projector

The invention relates to a device for the examination of an eye using a Scheimpflug camera and a slit light projector for slit images of an eye. The Scheimpflug camera and the slit light projector are carried by a stand, whereby the slit light projector and the scheimpflug camera are arranged rotatably about a common axis coinciding essentially with the optic axis of the eye. Such a device is improved so that without interruptions and returns of the Scheimpflug camera to an initial position, the eye can be scanned multiply by means of the device. This is achieved by the slit light projector and the Scheimpflug camera being freely rotatable about the axis through more than 360&deg;, and by a voltage supply to both the Scheimpflug camera and the slit light projector occurring through a transmitter.
