Compact Reticle/Mask Particle Detection System PR-PD3

Overview

The PR-PD3 offers excellent throughput, a dependable optical system, and functions that reduce false detections. These features are blundled in a compact package that is designed to minimize running costs. The PR-PD3 also demonstrates great versatility thanks to its 0.5μm detection sensitivity.

Features

  • The compact design.
  • Low maintenance and operating costs
  • Effective function for countering erroneous detection
