RAPID NX

The RAPID NX offers <15 ps pulses in a newly designed package that is not only cost effective, but also fit for the most demanding 24/7 industrial applications.

The RAPID NX is a next generation picosecond laser system that encompasses all features of the existing RAPID laser at a significantly reduced cost. Hence, it is ideally suited for precision micromachining applications where the ablation quality and system cost are of the highest priority.

High Power Industrial ps-Laser

The RAPID NX is designed for industrial micromachining and offers ultrafast machining capability at an unprecedented price point. The RAPID NX offers all the features of the RAPID-series lasers at a lower power level and entry price. The system is designed for demanding specialty marking, engraving and LED dicing applications. The included intuitive software controls all laser functions via internal embedded processor. An optional DLL allows the user to control the laser via an external network.
