  Details:

F-theta scan lenses for CO2 laser systems are mainly used for marking. They are used in conjunction with one or two axis galvo mirrors that enable the laser beam’ s fast positioning and precision focusing.

The main indicators of F-theta scan lens are scan field and focal length. Normallythe longer focal length, the bigger scan field. But blindly striving for scanning area will bring a lot of problems, such as light spots become thicker, distortion increases, etc.

So when users choose F-theta scan lens, both scan field and marking accuracy should be considered.

The scan lenses we provide have special design, which make the marking more efficient and precision with the same focal length.
