3.3 Laser safety
3.3.1 Safety switch (interlock) on the microscope
Two safety switches are integrated into the microscope us-
ing a laser safety kit option. These must be integrated into
the laser safety concept so that the light path of the laser
beam is interrupted when the interlock switch is opened.

Interlock switch (1) and (2)
Interlock switch 1:
An interlock switch is integrated on the Transmitted Light
arm and activated when the Transmitted Light arm is folded
back (interlock switch opens).
Interlock switch 2:
An additional interlock switch is also installed in the micro-
scope, which is activated (interlock switch opens) when
the beam path to the eyepiece is released.
Two equivalent interlock connectors, which lead to the
microscope's interlock switch, are attached to the back of
the microscope. The interlock connector of the microscope
must be connected to your laser beam interrupter.
