Abstract

A portable slit lamp with a built-in digital camera (2) and an illuminating diaphragm (11) enables a simultaneous visual observation and capturing of good quality photographs of the inspected eyes. In the course of eye examination the physician can take single images or sequences of images or moving pictures segments. A special illumination diaphragm (11) projects onto the eye an illumination slit of chosen form and in addition ensures an increased amount of light for photographing by comprising next to the slit two side openings having the form of a circle section. The constructional solution is such as to enable that the illumination diaphragm can be built into portable or stationary slit lamps designs. To enable the observation of the eye posterior a noncontact lens is attached onto the slit lamp in such a way that the focal point of the noncontact lens coincides with the focal point of the microscope objective and that the light beams passing from the noncontact lens onto the eye of the patient are parallel.
