consists of a main illuminator and a backup illuminator.
They are located in the illumination unit.
The main and backup illuminators consist of xenon lamps. The
light of the main and backup illuminators is lead to the optics
carrier via a fibre-optic cable through the base.
If the main illuminator fails, the plug of the fibre-optic cable is
switched over to the backup illumination.
