RAPID NX Lasers

☆☆☆☆☆ ( 0 rates ) 503
Price : Call

Code: #17721

Supplier: Coherent Inc

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.
