Key Advantages of Our Upgraded Boxed Protective Lenses
-
Upgraded Dust-Free Boxed Packaging: Each lens is individually packaged in a class 100 dust-free environment with anti-static, shock-proof and moisture-proof protection. Eliminates secondary pollution during transportation and storage, keeping the lens in optimal condition before use—no pre-cleaning required, direct installation.
-
Full Size & Full Power Coverage: Complete range of 35+ conventional and customized sizes with dedicated models for 0-15KW, 20KW, 30KW and 40KW lasers. Provides 1:1 precision fit for all mainstream fiber laser cutting heads and welding guns on the market.
-
Imported Optical Grade Fused Silica: Made from premium high-purity fused silica material with exceptional transmittance of ≥99.8% at 1064nm wavelength. Features ultra-low absorption to effectively reduce laser energy loss and ensure stable cutting and welding power output.
-
Upgraded Double-Sided Hard Coating: Both sides feature enhanced anti-reflection, anti-scratch and anti-spatter coating with excellent hydrophobic and oleophobic properties. Resists dust and welding slag adhesion, is easy to clean, and has a higher laser damage threshold.
-
Ultra-High Precision CNC Polishing: Ultra-smooth optical surface with strict thickness and parallelism tolerance control. Free of bubbles, impurities and burrs, ensuring uniform laser spot, avoiding beam deviation, and improving cutting and welding precision.
-
Broad Industrial Applicability: Suitable for 1064nm fiber laser cutting, handheld laser welding, automatic laser welding and robotic laser processing. Compatible with all common metal materials and widely used in various industrial fields.

Frequently Asked Questions
Q: How do I choose the correct protective lens size for my machine?
A: The required size depends on your specific laser cutting head or welding gun model. You can find the size information in your machine's user manual, or measure your existing protective lens (diameter and thickness). If you are unsure, please contact our sales team with your cutting head model number for confirmation.
Q: What is the advantage of the upgraded boxed version over bulk packaging?
A: Our upgraded boxed version provides class 100 dust-free independent packaging that protects the lens from contamination, scratches and moisture during transportation and storage. Lenses arrive in perfect condition and can be installed directly without pre-cleaning, saving you time and reducing the risk of damage during handling.
Q: What is the benefit of the double-sided hard coating?
A: The upgraded double-sided hard coating provides three key benefits: 1) Enhanced anti-reflection properties for maximum laser transmittance; 2) Improved anti-scratch and anti-spatter resistance; 3) Hydrophobic and oleophobic properties that make cleaning easier and extend service life by over 40% compared to ordinary lenses.
Q: How often should I replace my protective lens?
A: Replacement frequency depends on your usage intensity, material being processed and operating environment. Under normal conditions, protective lenses should be replaced every 1-2 weeks for high-volume production. Always replace the lens immediately if you notice any burns, cracks or significant spatter buildup.
Q: Can I clean and reuse a protective lens?
A: Yes, you can clean a lightly contaminated lens using isopropyl alcohol and lint-free optical wipes. However, once a lens has burns, deep scratches or significant spatter that cannot be removed, it must be replaced immediately to avoid damage to more expensive internal optical components.
