Laser Scanning system Lens

Scanning Laser System OpticsF-theta scan lenses play a major role in today’s leading-edge laser applications. II-VI manufactures scan lenses for CO2 laser systems that are used for marking, engraving, via hole drilling, and more.

In a typical scan lens configuration, the F-theta lens is used with one or two axis galvo mirrors that enable the laser beam’s fast positioning and precision focusing.

While standard focusing lenses deliver a focused spot to only one point, scan lenses deliver a focused spot to many points on a scan field or workpiece. They require special considerations in their design and use.

Scan lens applications include:

  • Marking
  • Engraving
  • Rapid prototyping
  • Drilling circuit board via holes
  • Cutting cloth
  • Cutting paper


Our II-VI scan lenses feature:

  • The finest optical materials in the world
  • Special housing designs to optimize performance
  • Wavelength options from 9.2 to 10.6 µm
  • Via hole drilling diameters from 75 to 300 µm
  • Designs featuring one to five optical elements
  • Optional protection windows
  • Low-loss AR coatings
  • Precision optical elements


Contact a II-VI sales representative to discuss your scanning laser optics needs.
