GÖTTINGEN, Germany, April 29, 2013 — Qioptiq has enhanced its Linos F-Theta Ronar line of lenses with a series offering wavelengths from 940 to 980 nm. Designed for laser system applications such as plastics welding, the lenses provide broadband antireflection coating, enabling a high damage threshold.
Features include transmission ≥97% in the 940- to 980-nm-wavelength range and ≥75% in the visible range (e.g., for inspection with camera systems). The laser damage threshold is up to 6 J/cm2 (e.g., at 1064 nm, 10-ns pulse length, 100 Hz).
The lenses offer stable, high-precision optomechanics for optimum spot quality over the entire scan field. Replaceable protective glasses are included, and focal lengths from 100 to 420 mm are available.
