F-Theta Lens

F-Theta Lens

This lens focused a laser beam scanned with a scanner, etc. It is used for high speed micro drilling of printed circuit boards, high speed marking of electronic parts and resin parts, etc.
This lens minimize distortion and make a laser beam incident almost perpendicularly to the work piece. It is suitable for processing such as laser micro drilling. This lens is suitable for markers, plotters, etc. of which you want to scan a wide area quickly.
The window is coated with super hard DLC (Diamond like carbon) and protects an F-Theta lens from back scatters.
