F-Theta-Ronar Lenses 440-460 nm

The LINOS F-Theta-Ronar Blue Line lens is 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.

This lens is 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, this LINOS F-Theta-Ronar Blue Line lens meets highest quality standards, making it suitable for a wide variety of blue laser light applications in laser material processing. Due to the blue laser wavelengths between 440-460 nm , the LINOS Blue Line F-Theta-Ronar lens is a perfect match for laser material processing of nonferrous metals such as copper, aluminum or other high reflective materials.
