Qioptiq, an Excelitas Technologies Company, announced the new LINOS F-Theta-Ronar 75mm telecentric lens, which features a focal length of 75mm at wavelengths from 515nm-540nm. The complete fused-silica lens enables the largest scan field available for large laser apertures of up to 27x27mm², making it ideal for use in laser material processing industries such as energy storage and micro/macro machining for high power or short pulse applications including structuring, welding and cutting.
The LINOS F-Theta-Ronar 75mm lens is optimized for a large entrance beam aperture up to 15mm resulting in a smaller spot size of 5μm over the scan field for high-power applications. Its focal length delivers high precision and spot quality to allow the smallest possible spot diameter. The new F-Theta-Ronar lens’ high-end angle corrected coating has been laser-damage threshold (LIDT) tested for ns @ 532nm and fs @ 515nm, making it usable for ultra-short pulse and high-power applications with constant transmission over the scan field.
Additional product attributes include:
- Screw thread M85x1
- Transmission over scan field ≥ 96 % at 515nm-540nm
- Laser-damage threshold (LIDT) coating: 20 J/cm² at 532nm, 8ns, 100Hz and 0.6J/cm² at 515nm, 204fs, 50kHz
- Includes interchangeable fused silica protective glass
The LINOS F-Theta-Ronar 75mm telecentric lens is one of many products that will be on display at Formnext 2019, November 19 – 22, 2019 in Frankfurt, Germany. Visit Excelitas booth Hall 12.0 B27 to learn more.
