F-Theta-Ronar Lenses 340-360 nm
These LINOS F-Theta-Ronar lenses are designed to achieve aberration-free imaging for UV laser wavelengths between 340 – 360 nm, allowing exceptionally small spot diameters over the full flat image plane. All lenses are made of premium fused silica for high-power and ultrashort-pulse laser material processing equipped with a sophisticated broadband and angle optimized coating.
A large variety of focal lengths and telecentric designs are available, making LINOS F-Theta-Ronar lenses suitable for a wide range of laser material processing applications. Manufactured with leading-edge production technologies to ensure long-term optical stability, LINOS F-Theta-Ronar lenses meet highest quality standards.
The LINOS low outgassing UV F-Theta lens f=330 mm is the first of its kind featuring stainless steel design in an off-the-shelf UV standard product to minimize potential contamination and extend product lifetime for optimal diffraction limited performance. This product offers higher durability to enable higher UV pulse energies and shorter laser pulses that are essential for laser material processing applications in the semiconductor, wafer processing and electronic display industries. Also available is a cost-optimized version of the 330 mm UV-F Theta lens made of colorless anodized aluminum with reduced outgassing behavior.
