10 times CO2 beam expander for laser marking machine. The laser beam expander has two purpose: expand the diameter of the laser beam, and reduce the divergence angle of the laser beam.

CO2 laser beam expander are widely used in laser marking, engraving, drilling machines. The Single-chip Flat-field Scanning Mirror has optimized the wide-angle and long focal-length light path, it is widely applied in wide scan range situation.The absorbability of Zinc Selenide to the infrared wavelengths is low, and can flitter visible light, it is the top choice of beam expander lens.
