Laser Window
DELN offer laser protection window for applications which require protecting laser output. High damage threshold (>15J/cm2) AR coating on both sides can minimize the reflections.
These laser windows are used in front of lasers for material processing in order to protect the laser optics from hot material drops.
Other coating or custom coating are available.
