Laser power is the central figure characterizing the laser beam and directly controls the performance of materials processing. However, the power indicated at the laser does not always reach the workpiece. Ab-sorption within the beam path at deffective components or changes within the calibration of the laser internal power meter may occur. Differences can be presented and documented easily with the CompactPowerMonitor (CPM) from Primes (Pfungstadt, Germany). Primes calibration service ensures long term accuray of the CPM.
The CPM joins high accuracy with compact design. The CPM is designed with plane absorber for the NIR and with the conical absorber for highest power density up to 5 kW/cm2 and the FIR range. The CPM can even be driven with deionised water determinates the laser power with high accuracy even with up-to-date laser sources in the multi kilowatt range.
The CPM product group with plane absorber consists of: CPM-F-1up to 1.4 kW, the CPM-F-10 up to 10 kW and the CPM_F-20 up to 20 kW. Optional adapters for many standard fiber coupler are available ready to measure the output directform the fiber output.
