The L-LENS-QUARTZ/25/4 is a 25mm-diameter, 4mm-thick quartz protective window designed for fibre-laser optical systems. Installed in the laser head or torch, it helps shield sensitive internal collimator and focusing lenses from dust, smoke, debris and molten-metal spatter. Its anti-reflective coating supports efficient transmission of the fibre-laser beam while reducing unwanted reflections. This replaceable optical consumable helps maintain consistent laser performance, beam clarity and processing quality during demanding cutting, welding or cleaning applications. Replace the window when it becomes scratched, contaminated or damaged, ensuring that the dimensions match your machine\u2019s lens holder before installation.
