The protective lens in a fiber laser machine; (Laser welding machines and laser cleaning machines) acts as a safeguard against debris, splatter, and other contaminants, preventing damage to critical components of the laser head ensuring the focusing lens remains protected.

• High-quality pure quartz is utilized, offering exceptional optical, thermal, and mechanical properties.
• Both sides are coated with a high-threshold anti-reflective film to minimize light energy loss due to reflection, reduce slag adhesion, and prevent lens breakage.
• The quartz undergoes multiple processes, including cutting, polishing, and finishing, ensuring high-temperature resistance and strong durability against laser exposure.
