F-Theta Scanning Lenses

F-Theta Scanning Lenses
  • Designed for Nd:YAG (1064nm, 532nm and 355nm) and CO2 (10.6μm) Laser Sources
  • Provides a Flat Field at the Image Plane

F-Theta Scanning Lenses are commonly used in laser marking, engraving, and cutting systems. Used in conjunction with a galvanometer, beam expander, and Nd:YAG or CO2 laser source, F-theta lenses are designed to provide a flat field at the image plane of the scanning system.

Our Nd:YAG F-Theta Lenses feature multiple elements for the ultimate in image resolution. An air-spaced design and high efficiency AR coatings guarantee excellent throughput and durability. An industry-standard M85 threading on all F-theta lenses allows for easy mounting and simple retrofitting of OEM systems.

Our Nd:YAG F-Theta Lenses feature pulsed laser damage thresholds up to 5J/cm2 @10ns, or 1MW/cm2 (CW).

For diffraction-limited focusing performance at the image plane, the entire entrance pupil of the F-Theta lens should be utilized. Our 3X and 5X TECHSPEC® Fixed Power Laser Beam Expanders are ideal complements to our F-Theta lenses.
