F-Theta-Ronar 440 – 460 nm, 262 mm

LINOS F-Theta-Ronar Lenses 440 – 460 nm

The LINOS® F-Theta-Ronar Blue Line lenses are designed to achieve aberration-free imaging over the entire flat image plane for laser wavelengths between 440 – 460 nm. Exceptionally high entrance beam diameters allow minimum spot size in the image plane. All lenses are made of premium fused silica for high power laser material processing equipped with a sophisticated broadband and angle optimized coating. 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 blue laser light applications in laser material processing.  

Due to the blue laser wavelengths between 440-460 nm , LINOS Blue Line F-Theta-Ronar lenses are a perfect match for laser material processing of nonferrous metals such as copper, aluminum or other high reflective materials.

  • Fused-silica design
  • Focal length 262 mm, tolerance ±1 %, additional focal lengths coming soon
  • High end broadband, low absorption coating 440 – 460 nm
  • Transmission ≥ 96 %
  • Includes interchangeable fused- silica 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.
