F-θ scan lenses play a major role in many of today’s leading-edge laser applications. Cloudray manufac-tures scan lenses for laser systems that are used for marking, engraving, via hole drilling, and more.
In a typical scan lens configuration, the F-8 lens is used with one or two axis galvo mirrors that enable fast positioning and precision focusing of the laser beam.
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 also require special considerations in their design and use.
