9.6 Laser Coupling Unit (LCU)
In the laser coupling unit (LCU), there are up to four pulsed lasers. It combines and couples
one or more pulsed VIS laser beams (e.g. 440 nm up to 640 nm) into a polarization-
maintaining single mode (PM-SM) laser (
Figure 25 ). This laser is coupled into the
multifunction port (MFP) of the SP8 scan head.
In the UV range (e.g. 405 nm) a separate laser output is used that is coupled to the UV port
of the SP8 scan head.

WARNING Risk of permanent eye and skin damage from laser radiation
The laser coupling unit must not be opened. The adjustment of the laser
beam and the coupling must be carried out by a service technician.
