laser protective window


He Rui optics' Laser protection windows, also known as laser window plates or laser dust shields, are primarily used in applications such as laser cutting, welding, marking, and engraving. The main function of these windows is to block debris splatter, preventing it from damaging the focusing lens. Laser protection windows are typically made from materials with high damage thresholds and coated on both sides with anti-reflective coatings to reduce reflection and improve transmission.


laser protection windows are widely used in laser cutting, welding, marking, and other applications, effectively protecting the optical elements within laser equipment and enhancing processing precision and product quality.
