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.
LINOS F-Theta-Ronar lenses are manufactured using advanced production technologies to ensure long-term optical stability and meet the highest quality standards. They are ideal for a wide range of blue-laser applications in laser material processing.
Operating at blue laser wavelengths between 440 and 460 nm, LINOS Blue Line F-Theta-Ronar lenses are well-suited for processing nonferrous metals including copper, aluminum, and other highly reflective materials.
All lenses support learger beam diameters and various mirror distances, which influence affect scan fields and spot sizes. Please contact us to discuss your specific requirements.
