FT SERIES: FIBER LASER F-THETA LENSES

FT Series is a family of F-Theta scan-lenses specifically designed to fit fiber-laser sources.
These lenses accept input beam diameters as large as 15 or 20 mm without any vignetting or focus decay over the entire scan area.
The optical system is achromatized over a wide wavelength range (60 nm) in order to keep the spot size minimum even if the laser source bandpass or peak wavelength could change.
The mirror distances are tailored to fit most standard scanheads.
Very small spot size, close-to-zero distortion and very wide scan angle make these lenses the state-of-the-art choice for any power laser application.

KEY ADVANTAGES:

  • VERY LARGE APERTURE: FT Series are suitable for even the largest beam diameters delivered by fiber-laser sources
  • ACHROMATIZATION: FT Series maintain the focus quality even when the emission wavelength changes
  • VERY HIGH OPTICAL PERFORMANCES: spot size, distortion, field flatness and scan angle are all set at maximum
