UV F-theta Lenses

The 355nm UV F-theta lenses focus the collimated laser beam on one point to increase the energy density of the laser beam. When the direction of the incident beam changes, F-theta lenses can still maintain a spot with the same relative size and energy density, ensuring process efficiency is maintained.

Product introduction

  •   The 355nm UV F-theta lenses focus the collimated laser beam on one point to increase the energy density of the laser beam.
