We offer fixed,adjustable and continuous zoom beam expander to correct the laser beam divergence.Beam expanders with water cooling mechanism are also available in stock to provide a better protection under high power application.The beam expanders are usually working together with F-θ scanning lenses to create a flat filed at the image plane.

Good transmitted wavefront characteristics:
Fine performance on center rotation
