Page 10: About This Operating Manual
When the FocusMonitor FM+ is being operated, the irradiation must be fully absorbed be- hind the measurement zone. Fire bricks or other partly-absorbing surfaces are not suitable. X Use an adequate absorber. Dependent on the application, PRIMES offers suitable absorbers, such as the PowerMonitor PM 48/100. -
Page 11: Introduction
FocusMonitor FM+ Introduction System description The FocusMonitor FM+ is an opto-mechanical scanning measurement system for analyzing continuous irradiation. The laser beam is scanned with a rotating measuring tip on the x-axis. Using the horizontal and vertical carriers, the measuring tip is moved along the y- and z-axes so that the beam characteristics of the focused laser beam can be spacially measured. -
Page 12: Measuring Principle
FocusMonitor FM+ Measuring principle The FocusMonitor FM+ is designed to analyze the focused laser beam. The device measures the spatial power density distribution in the focus range of the processing optics. Using this information, the system calculates the focus radius, focus position in the space, and the beam quality factor M The power density distribution in the focus is measured with the FocusMonitor FM+ using a rotating measur- ing tip that scans the beam cross section line by line in the y-direction. -

Page 18: Align The Focusmonitor Fm
FocusMonitor FM+ Align the FocusMonitor FM+ 7.4.1 Device's position in relation to the laser beam For the FocusMonitor FM+, the beam must enter vertically to the x-y-plane (see Fig. 7.6 on page 18). The vertical alignment (z-axis) is primarily dependent on the expected focal length. The maximum vertical stroke of the measuring device is 120 mm. - Page 19 FocusMonitor FM+ 1.
