11.4.2 Exchange protective window in front of the power output aperture
• Observe the warning messages above.
• Keep the protective window free from contaminations.
• Do not touch the plane surface of the protective window when putting it in!
The protective window protects the optical elements behind it from contaminations. A polluted protec-
tive window does not affect the function of the measuring objective. However, the increased scattering of
the laser light leads to a heating up of the protective window and the housing which can finally result in the
destruction of the protective window itself. This can damage sensitive optical components in the measuring
objective. Therefore, a contaminated protective window has to be exchanged immediately.
