fθ lenses

fθ lenses

 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.

Features
 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.

Use
 High-speed drilling of printed wiring boards
 High-speed marking of electronic components
 High-speed marking of resin parts
 Laser processing
 Laser drilling
 Laser welding of synthetic materials
 Laser cutting
