FocusMonitor FM+
Laser radiation warning
During the measurement the laser beam is reflected from the rotating measuring tip. This produces scattered
or directed reflection of the laser beam (laser class 4). Depending on the wavelength of the laser, the reflected
beam is usually invisible.
To avoid injury from the reflected laser beam, no one should be in the hazardous area where the measurement
is taking place. The hazardous area must be defined before operation of the FM+.
During operation of the device, the laser radiation must be fully absorbed after passing through the measurement
zone.
The radiation is not absorbed by the FocusMonitor itsself. A suitable absorber must be used for this purpose.
Suitable PRIMES laser power meters can be found in chapter 7.2.5 „Connecting a FM+ to a laser power meter"
on page 23.
When working with the device, people in the hazardous area must protect themselves by taking the following
protective measures.
