IMPORTANT NOTE
The slit lamp will be automatically switched off by the system after 3 minutes.
There are four types of apertures available which can project different slit sizes, as well as diffuse
illumination towards the patient’s eye. The different apertures are labelled as:
S (25 µm slit width)
M (50 µm slit width)
L (100 µm slit width)
D (10 mm diffuse
illumination
Figure 4-12: Apertures for the slit lamp (sample)
To change the slit size or to change to the
diffuse illumination pull out the currently
used aperture module and insert the desired
module into the slit lamp.
The apertures are kept in a shelf, which is
fastened to the laser tower underneath the
monitor.

WARNING!
The new LED is a very powerful light source, so it is very dangerous for the
human eye to use higher settings even if there is an aperture with a slit inside
the slit lamp. For applications on the human eye it is recommended to use the
slit lamp always together with an installed slit aperture. Make sure that slit
lamp is switched off before slit aperture is exchanged.
If no aperture is used or the aperture D10 is inside the slit lamp use only very
low values of brightness for illumination of the human eye. If higher values of
brightness are needed the application time must be reduced to some seconds
only.
