The LINOS F-Theta-Ronar 265-mm lens from Qioptiq features a wavelength of 1900 to 2000 nm.

The small, fused silica lens for scanning areas up to 177 × 177 mm² at a detailed wavelength is ideal for high-power applications requiring reduced thermal focus shift, including melting processes such as polymer welding, clear plastic welding and 3D structuring/selective laser etching of glass and silicon.

Featuring a shorter focal length compared to existing F-Theta-Ronar scan lenses, the 265-mm lens for 1900 to 2000 nm results in smaller overall size. It also delivers a large scan field of up to 177 × 177 mm² with the same minimum spot size of 94 µm, as compared to existing scan lenses with a focal length of 354 mm for 1900 to 2000 nm.
