WSX Original Fiber Laser Collimating And Focusing Lenses

The collimating lens catches the extremely divergent output from the optical fibre and generates a parallel (collimated) beam with less divergence, facilitating modest propagation distances.

Collimating and focussing lenses in fibre laser cutting heads are highly susceptible to contamination. Consequently, most fibre laser systems utilise protective windows to shield the focussing lens from pollution. Collimating and focussing lenses in fibre laser cutting heads are highly susceptible to contamination. Consequently, most fibre laser systems utilise protective windows to shield the focussing lens from pollution. The protective window is situated before the focussing lens and acts as a barrier between the lens and the metal sheet.
