The role of f theta lens
• Focusing the collimated laser beam on a smaller area of the focal point increases the energy density of the laser beam and improves the capability and efficiency of laser processing.
• Converts the change of laser beam direction by the oscillator into the change of focal point on the position of the processed material, thus realizing high-speed and precise laser processing machining.
Features of f theta lens
1. 1064 nm design wavelength for Nd:YAG laser system.
2. Flat image plane.
3. Large scanning range: 70 mm x 70 mm to 300 mm x 300 mm.
4. F-Theta distortion less than 0.1% or 1.3%.
5. Optional M85 x 1.0M39 x 1.0 thread version.
6. Air gap design.
7. All optical elements are coated with transparency-enhancing film.

Common applications of f theta lens
• Perforating and precision cutting of metal or pottery (e.g. micro holes in PCBs)
• Plastic welding (e.g. fusing plastics without filler material)
Shaping and piercing of metal or non-metallic materials (e.g. openings/vents)
• Marking (e.g. smart cards, integrated circuits, printed boards, keyboards and dashboards, etc.)
• Cleaning of industrial products (e.g. lenses) or restoration applications (e.g. monuments, etc.)
