F-theta scan lens play a major role in many of today’s leading-edge laser applications. 

Lastlaser manufacture scan lenses for laser system that are used for marking, engraving, drilling and more. In a typical scan lens configuration, the F-theta lens issued with one or two axis galvo mirrors that enable fast positioning and precision focusing of the laser beam.

F-theta lens, known as focus lens and field lens, is an important component in laser marking machine, which focus the laser beam on the marking surface. It has several performance metrics as below:

1.Scan Field

2.Focal length

3.Working wavelength
