The latest edition to the popular Linos product line delivers increased scan field and small spot size for laser material processing industry. It features a bigger scan field (28 by 28 mm²) with 5µm spot size, making it ideal for micromachining in the semiconductor, electronic and display markets for ultraviolet-pulsed laser applications.
The UV F-theta-ronar Lens for 340–360 nm includes an angle corrected coating for stable transmission over the entire scan field and for a more stable focus position and process. The fused silica Linos 70 mm lens is one out of many available lenses from Qioptiq’s UV series, which includes additional telecentric and non-telecentric lenses with varying focal lengths available to meet customer specifications. The new UV F-theta-ronar Lens product features:
- Telecentric lens with special optical design and advanced technology for minimized spot size variation.
- Fused silica to deliver high transmission and reduced thermal focus shift.
- Angle-optimized broad band coating to enable the use of various laser sources with different wavelengths and low absorption.
- 5 µm spot size capability for microstructures, holes and processes.
“We are extremely excited to expand our range of scan lenses with the introduction of the UV Linos 70 mm F-theta-ronar Lens for 340-360nm,” said Matthias Koppitz, Application Engineer at Qioptiq. “Its 100% measured performance values for variables such as spot size, transmission and focal length meet the growing demands for precision from our customers across the laser material processing industry.”
