Function of the focused beam measuring system with MicroSpotMonitor
. Camera based measurement of focused laser beams.
. MicroSpotMonitor is equipped with 3 motorized axes (2x2x35mm³) as well as a water-cooled absorber and internal optics to determine propagation properties of focused laser beams in the Green to NIR range.
. Measurement parameters include: Power density distribution, focus position, focus dimensions, Rayleigh length, divergence, beam quality (SPP/M²).
. The system has 3 internal beam paths to adjust the magnification of the objective.
. Wavelength: 1064nm, 532nm
. Maximum permissible average power:
500 W at 1064 nm
100 W at 532 nm
. Power range 10W - 10kW with Beam Monitor
. Decisive for the validation of the individual wavelengths is the suitability of the objective (MOB).
. Beam dimensions: 20um-600um
. MOB 5-fold (NIR,VIS)
- Measuring objective, diffraction limited, with 5 X fold magnification
- 1.7x with field objective
- 8.5x with increased image
