- Enabled to detect particles as small as 0.35 µm
- Multi-stage sorter
- Easy operation DMS
- Provides top and bottom views of surface particles.
The PR-PD2 Particle Detection System enables fine particle detection down to 0.35μm and also boasts a multi-stage sorter plus has a full range of communication functions. High-throughput measurement is possible on all surfaces from basic reticle and mask to glass and pellicle.
