F Theta Lens For 1064 Nanometer Fiber Laser Machine Scanning 300 By 300 Millimeter FL420 Millimeter FL380 Millimeter M85 Pro Grade Ultra Fine Marking And Engraving Via Hole Drilling Capability
✔️ 1064nm f-theta lens for fiber lasers, 300x300 mm field, single unit
The F-Theta lens for 1064nm fiber lasers is a precision scanning optic used in marking, engraving, and via-hole drilling on metal and ceramic substrates. It's a staple in fiber laser marking machines for industrial manufacturing and electronics prototyping.
✅ 300x300 mm field of view (11.8 x 11.8 in) for wide scanning
✅ High transmittance up to 97% with AR coatings for clean engraving
✅ M85x1 threading for quick installation in most laser marking machines
✅ Heat and wear resistant design to reduce thermal focus shift
✅ Compatible with common fiber lasers (Raycus, JPT, MOPA) for easy upgrades
💡 What is an F-theta lens used for in fiber laser marking systems?
Used to map the laser beam cleanly across a flat field for consistent marks.
- Increases marking accuracy across the 300x300 mm field (11.8 x 11.8 in).
- Maintains uniform spot size as the beam scans across the area.
- Works with typical fiber lasers for easy upgrades.
