LINOS F-Theta-Ronar Lenses 940 – 980 nm
The LINOS® F-Theta-Ronar lenses are designed to achieve aberration-free imaging for laser wavelengths between 940 – 980 nm, allowing exceptionally small spot diameters over the entire flat image plane. A large variety of focal lengths in optical glass design are available. Manufactured with leading-edge production technologies to ensure long-term optical stability, LINOS F-Theta-Ronar lenses meet highest quality standards, making them suitable for a wide variety of laser material processing applications.
- Focal lengths ranging from 100 mm to 420 mm, tolerance ±1 %
- Transmission ≥ 97 %
- Transmission ≥ 95 % at VIS-range
- Laser-damage threshold coating up to 6 J/cm² at 1064 nm, 10 ns, 100 Hz
- Includes interchangeable protective glasses
All lenses can be used with enlarged beam diameters and various mirror distances. Scan fields and spot size diameters will change accordingly. Please contact us to discuss your specific requirements.
