Mounting
4.2.1 Deflector mirror
With the WSU/WEU26@3 and deflector mirrors, access protection on several sides can be
realised (Fig. 10).
The usage of deflector mirrors reduces the effective scanning range of the system
WSU/WEU26@3 as specified in Tab. 7.
The usage of mirrors (Fig. 11) requires very precise alignment. It is recommended to use
the AR60 laser alignment aid. The AR60 alignment aid is available as an accessory (Tab.
17, page 36).
