F-Theta-Ronar 1030-1080 nm, f=420 mm

LINOS F-Theta-Ronar Lenses 1030 – 1080 nm

The LINOS® F-Theta-Ronar lenses are designed to achieve aberration-free imaging for laser wavelengths between 1030 – 1080 nm, allowing exceptionally small spot diameters over the entire flat image plane. A large variety of focal lengths in optical glass or fused silica designs for high power and ultra-short-pulse laser applications as well as telecentric versions are available, making LINOS F-Theta-Ronar lenses suitable for a wide variety of laser material processing applications. Manufactured with leading-edge production technologies to ensure long-term optical stability, LINOS F-Theta-Ronar lenses meet highest quality standards.

Due to their extra low absorption coating and their extremely small thermal focus shift, LINOS fused silica F-Theta-Ronar lenses are a perfect match for high power applications such as metal welding or cutting as well as for ultrashort-pulse laser applications and hence, the first choice in semiconductor manufacturing.

  • Fused-silica and optical-glass designs
  • Telecentric versions available
  • Focal lengths ranging from 70 mm to 420 mm, tolerance ±1 %
  • Transmission ≥ 96 % with good performance in VIS-range
  • Laser-damage threshold coating up to 40 J/cm² at 1064 nm, 12 ns, 100 Hz and up to 0.9 J/cm² at 1030 nm, 291 fs, 5 kHz
  • Low absorption coating for fused silica lenses ≤ 20 ppm at 1064 nm
  • Includes interchangeable protective glasses

All lenses can be used with enlarged beam diameters and different mirror distances. Scan fields and spot size diameters will change accordingly. Please contact us to discuss your specific requirements.

For 3D drawings and datasheets for each lens please refer to Q-Shop - Docs + Drawings.
