LC-Tec has a long history of activities related to eye protection during welding. The first LC-Tec company produced automation equipment for manufacturing of LC shutters used in auto-darkening welding helmets. Today our fast optical shutters are used to attenuate light from the welding arc in laser welding microscopes and in cameras monitoring the welding process.
Different shutter models are provided depending on the requirements. The FOS model offers high contrast between open and closed states even at moderate drive voltage amplitude, while the X-FOS(G2)-CE model incorporates a dual-cell structure in order to achieve exceptionally high light extinction in the closed state giving an open to closed state contrast of ≥120,000:1. Both models are available in -AR versions for excellent image quality.
