CO2 Laser Optical Lenses

CO2 laser cutting can be applied to cut almost all metal or non-metal materials. The optical system includes laser resonator cavity optical system (including rear mirror, output coupler, reflecting mirror and polarization Brewster mirrors) and outside beam delivery optical system( including reflecting mirror for optical beam path deflection, reflecting mirror for all kinds of polarization processing, beam combiner/beam splitter, and focusing lens).

YANNTEK Laser marking system can be applied to the marking of all non-transparent materials. General optical system: Expanding the beam through the beam expander to improve the divergence angle, after the beam combines the indicator light into the galvanometer system for beam deflection and scanning, finally, the workpiece is scanned and focused by the F-THETA scan lens.
Laser marking optical components mainly include beam expander and F-THETA scan lens.The role of the beam expander is to enlarge the beam diameter and reduce the beam divergence angle. F-Theta scan lens achieves uniform focusing of the laser beam.They are widely used in drilling and marking fields.
