Fθ lens is used when a galvano mirror or polygon mirror is used to scan a laser beam in two dimensions.
The lens distortion characteristic is used to scan the focused spot of the beam scanned by the mirror's constant velocity rotational motion at a uniform speed on the focal plane.
Good focus spot characteristics with minimal aberration
Interchangeable window protects the lens from scattered objects generated from the workpiece
Able to customize other wavelengths, multiple wavelengths, long working distances, wide scan areas, etc.
High-speed drilling of printed wiring boards
High-speed marking of electronic components
High-speed marking of resin parts
Laser welding of synthetic materials
Laser processing machine, solar cell manufacturing and inspection system, semiconductor manufacturing and inspection system, LCD manufacturing and inspection system, etc.
