NOTICE
Short working distance
When opening the chamber door, the microscope or specimen can be damaged if the speci-
men stage is at a short working distance. If a BSD detector is inserted, it can be damaged as
well.
4
Always retract any retractable detectors before opening the chamber door.
4
Always move the specimen stage to a long working distance before opening the chamber
door.
NOTICE
Contamination caused by fingerprints
Contamination caused by fingerprints can lead to vacuum deterioration or prolonged pumping
times.
4
Always wear lint-free gloves when touching the specimen, specimen holder, or stage.
2.3.8 Radiation Hazards
CAUTION
Laser radiation class 1M
If the optional Raman Spectrometer is installed, then diffuse laser reflection may be visible
when the chamber door is open.
4
Do not view directly with optical instruments into the laser reflection.
WARNING
Radiation hazard due to X-rays
X-rays are generated inside the microscope during operation. This is unavoidable because elec-
trons are accelerated by voltages up to 30 kV.
4
Do not remove any parts around the column and chamber that are essential for radiation
protection.
4
Use genuine ZEISS parts exclusively.
4
Ensure that all local safety and X-ray protection regulations are met.
4
Only authorized ZEISS service representatives are allowed to service the microscope.
The microscope is equipped with several radiation protection devices, which, under regular oper-
ating conditions, ensure that the microscope operates in accordance with the German X-ray pro-
tection regulation (RöV), the German radiation protection regulation (StrSchV) as well as with the
EC Directive 2013/59/EURATOM.
In the EU, the operation of the microscope is permission-free as the following requirements are
fulfilled:
§
The acceleration voltage is limited to 30 kV.
§
The local dose rate at a distance of 0.1 m from the accessible surface of the microscope does
not exceed 1 μSv/h.
§
A respective label is attached to the microscope.
Outside the EU, the user of the microscope has to comply with the local regulations of the coun-
try where the microscope is operated.
