The laser protection window is mainly used to block debris splashes during laser cutting and prevent splashes from damaging the lens. Both sides are coated with a high damage threshold (>15J/cm2) transmittance enhancement film to minimize reflections. Widely used in laser cutting, laser marking and other applications. Shapes are round, square, cylindrical, and wedge shaped. Typical uses are in YAG and CO2 laser systems.
