The most sophisticated and advanced camera based beam profiler for high power beam characterization.

The MicroSpotMonitor MSM+ HB is designed to meet market requirements of constantly increasing power levels of high brilliant laser sources. The camera based system measures all relevant parameters of a focused laser. The MSM+ HB measures the power density distribution with the highest resolution and accuracy. Developing new laser sources, optimizing the optical path of focusing heads or verifying the performance of lasers in processing machines has never been that easy and reliable.

Your benefit

The new “plus generation” of our established MicroSpotMonitor provides higher measuring rates, enhanced algorithms and new measuring modes. Fully automatic caustic measurements and new features within our LaserDiagnosticsSoftware LDS increase the usability for basic measurements, while providing detailed information for in-depth analyses of your beam profile.

Tech Corner

The MicroSpotMonitor MSM+ HB is the most sophisticated and advanced camera based measuring device for high power lasers available on the market. With its unique design and its perfectly chosen components and optical elements the MSM+ HB is the ideal fit to attenuate and image a laser beam at up to 20 kW multi- or 10 kW single mode.

Our HighBrilliance measuring objective offers 4.5 fold magnification and is designed to reduce self induced focus shift to a minimum (~ 5 % / zR*kW SM). Additional beam splitters within the main housing as well as a filter wheel equipped with selectable neutral density filters enlarge the range of measurable power levels. Furthermore the MSM+ HB is equipped with two selectable internal objectives, expanding the possible magnification to 1.8 or 7.1 fold.

For measuring the caustic of a focused laser, the internal axes are moving the complete optical setup along the propagation of the laser. With its optional mount for fiber sockets, it is possible to measure the influence of a focusing head on a fiber laser with the MSM+ HB.

Thus, the propagation of a fiber guided laser can directly be measured. Deviations between the fiber and the focus measurement can be displayed and evaluated within the PRIMES LaserDiagnosticsSoftware LDS.

With an optional PowerLossMonitor PLM connected to the water circuit of the MSM+ HB, temporally resolved information on the laser power can be provided. An integrated safety circuit monitors the condition of the equipment and will immediately shut off the laser in the event of a fault.


Laser systems equipped with single or multi mode fiber lasers at power levels up to 20 kW can be surveyed in great detail. Power density distributions along the propagation of the focused or fiber guided laser will enable an easy root cause analysis. Distortions, aberrations or, more common, spatters and defects on optical surfaces are directly detectable.
Appropriate countermeasures can be initiated in a targeted and immediate manner.
