LINOS F-Theta-Ronar Lenses 1900 – 2000 nm
The LINOS® F-Theta-Ronar lenses are designed to achieve aberration-free imaging for laser wavelengths between 1900 – 2000 nm, allowing exceptionally small spot diameters over the entire flat image plane. All lenses are made of fused silica for maximum transmission values. 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.
LINOS fused silica F-Theta-Ronar lenses designed for the wavelengths 1900 - 2000 nm lenses are a perfect match for polymer welding, 3D structuring and selective laser etching of glass and silicon. Additional applications include laser processing in the semiconductor industry, micro-machining as well as ceramic and plastics.
- Fused-silica designs
- Focal lengths ranging from 265 mm to 437 mm, tolerance ±1 %
- Transmission > 95 % at 1940 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.
