ESL NWR193 Laser Ablation System

The NWR193UC is the 4th generation, high-performance, ArF excimer based laser ablation system from ESL’s Laser Ablation Division. Utilization of a short pulse width 193nm excimer laser source provides highest peak power for efficient ablation of all materials to produce small particles that can be efficiently transported and ionized by the ICP. The result – higher sensitivity, improved stability, and less fractionation.
