Description
The laser protection window is mainly used to block debris from splashing during laser cutting and prevent splashes from damaging the lens. Anti-reflection coatings with high damage threshold (>15J/cm2) are plated on both sides to reduce reflections. It is currently widely used in light cutting, laser marking and other applications.
