Product Description
Laser protective windows are mainly used to block spatter and debris during laser cutting, preventing damage to the lens caused by splashes. Both sides are coated with high damage-threshold anti-reflection coatings (>15 J/cm²) to minimize reflection. They are widely used in laser cutting, laser marking and other applications.
