CO2 Laser Scanning Lens

CO2 laser scanning lens is ideal for use in combination with galvanometer in a laser scanning system for a variety of laser processing tasks like laser engraving, laser cutting, laser drilling, laser marking and laser scribing.

SPT laser scanning lenses produce a flat image plane and a spot size that suffers minimal distortion. A low F-theta distortion (<1%) creates geometrically correct scanned images that do not require extensive post-image processing. Our CO2 laser scanning lenses deliver the highest resolution, smallest spot sizes, tightest tolerances and best lens durability in the optics industry.
