We need the protective lens (protective windows) to protect the focusing lens and the collimating lens to ensure the optic system working stability during laser cutting. Because it protects focusing lens and collimating from back spatter and debris.
The protective lens is positioned between the lens and the metal sheet. Obviously that it is the most consumed optical element in fiber laser cutting head.
