Abstract
A device is described for the integration of operating light and of monitoring and/or target light into an ocular examination instrument, for example a split lamp instrument, whose lamp and monitoring instrument can be rotated through a vertical axis drawn through the eye to be examined. In the device according to this invention the operating light beam and the monitoring and/or target light beam are directed in a strictly coaxial relationship. The coaxial light beams are first introduced into the axis of the split lamp designed as a concave axis, then deflected by a first optical apparatus out of the revolution axis in an almost vertical direction into the holder of the monitoring instrument and in this holder are deflected almost parallel to the revolution axis and finally integrated into the beam path of the monitoring instruments outside the revolution axis by a third optical apparatus.
