Top Quality Fiber Laser Protective Lens from ZPLASER
The fiber laser protective lens is located above the focusing lens; it serves to block dust, metal spatter, slag, and other contaminants, thereby protecting the internal optical components of the laser head.
Characteristics of ZPLASER'S Protective Lens
Optical-grade fused silica: Resistant to high-intensity laser irradiation, high temperatures, and high pressures; highly resistant to cracking.
High Light Transmission: Both sides feature anti-reflective, anti-scratch, and anti-spatter coatings, effectively reducing optical energy loss and ensuring stable focal power.
45° safety chamfer design: Finely chamfered edges prevent hand scratches during replacement or installation.
Double-sided anti-reflective coating: Enhances scratch and spatter resistance, reduces surface reflection, improves effective transmission, and extends service life.
Dust-free individual packaging: Ready for immediate installation upon opening, preventing secondary contamination.
Multiple size options: Protective lenses available in various diameters and thicknesses to fit a wide range of laser cutting and welding heads from different brands and models.

Operation & Maintenance Guidelines
The cleanliness of the protective lens directly affects the service life of the laser head. Proper handling and maintenance can help extend the lens replacement cycle.
1. Install in a Clean Environment
Replace the protective lens in a relatively clean environment with minimal airborne dust or particles.
2. Wear Protective Gloves
Always wear clean finger cots or powder-free gloves when replacing the lens. Never touch the optical surface directly with your fingers.
3. Handle by the Edges
When handling the lens, hold it only by the outer edge. Avoid touching the optical surfaces.
4. Clean Properly
Use isopropyl alcohol (IPA) and lint-free optical wipes for cleaning. Do not clean the lens in circular motions or apply excessive pressure.
5. Inspect Regularly
If you notice coating damage, persistent burn marks, or deep scratches that cannot be removed through proper cleaning, replace the lens promptly to prevent reflected laser energy from damaging internal collimating or focusing optics.
