User Interface
All user interface ports, except the nosepiece module GaAsP NDD 2 channels, are equipped
with a safety interlock system which warrants laser safety. These interlock devices must not be
manipulated. Other interfaces not described here are service interfaces and are only to be
operated by authorized ZEISS service personnel. The following devices can be mounted and
dismounted by the user or are accessible by the user:
−
Halogen lamp
−
Transmission PMT
−
Switching Mirror
−
NDD's (see corresponding system
manual for details)
−
BiG.2
−
GaAsP NDD 2 channels
10.1
Mounting and Dismounting Lamps, T-PMT and Switching Mirror
The ports of the lamps, the switching mirror and the transmission T-PMT are equipped with hardware
interlock devices which have to be operated in the following way:
Interlock with sensor ring and contact ring:
Fig. 17
Sensor ring mounted to the inter-
face ports on the microscope side
Fig. 18
Contact ring mounted to the lamp,
T-PMT or switching mirror
The interlock is working when the sensors of the sensor ring (Fig. 17/
1
) are depressed by the pins on the
contact ring (Fig. 18/
1
). Whenever this is not the case, for example if the distance between the two
devices is too large, the laser will be blocked and the system cannot be used.
In case the system is not operating following the removal or attachment of any device on a port
with safety interlock check again the connection of the Contact ring to the Sensor ring.
