At Rayno Laser, we understand that the heart of a reliable handheld laser welding system lies not only in the laser source but also in the critical components that maintain its precision and longevity. Introducing our high-performance Protective Lenses for Handheld Laser Welding Machines – the essential consumable designed to safeguard your equipment and ensure consistent, high-quality welds day after day.

Designed for the Demands of Handheld Welding

Handheld laser welding combines power with portability, but this exposes the internal optics to increased risks from spatter, dust, and debris. Our protective lenses serve as the first and most crucial line of defense for your machine’s focusing lens and other sensitive optical elements. By absorbing contaminants, they prevent costly damage and maintain optimal beam quality for clean, strong, and precise welds.

Key Features & Benefits:

• Uncompromising Optical Clarity: Manufactured from premium-grade, laser-grade fused silica or high-quality optical glass, our lenses offer exceptionally high transmission rates. This ensures minimal laser power loss, allowing your machine to operate at its intended efficiency and speed.

• Superior Coating Technology: Features advanced anti-reflection (AR) coatings on both sides. These coatings not only maximize laser energy throughput but also minimize hazardous back-reflections, enhancing overall system safety and stability.

• Exceptional Durability & Resistance: Engineered to withstand the intense thermal shock and mechanical stress characteristic of welding environments. They provide excellent resistance to metal spatter, slag, and common workshop contaminants, extending the service life of your core optics significantly.

• Precision Engineering for Consistent Results: Each lens is crafted to precise tolerances, ensuring perfect flatness and parallelism. This guarantees a consistent focal point and a stable, high-quality welding spot, which is critical for achieving uniform weld seams and penetration.

• Easy & Quick Replacement: As the most frequently replaced consumable, our protective lenses are designed for user-friendly maintenance. They allow for swift and simple replacement, minimizing machine downtime and keeping your productivity high. Compatible with most major brands and models of handheld laser welders.

• Cost-Effective Protection: A minor investment in a quality protective lens prevents catastrophic damage to the far more expensive focusing lens and internal optical assembly. Regular replacement of the protective lens is the most economical strategy for long-term equipment care.

Ideal For:

• All models of handheld fiber laser welding machines.

• Applications involving stainless steel, carbon steel, aluminum, copper, and other metal alloys.

• High-spatter environments and demanding production schedules.

• Workshops and fabricators prioritizing weld quality, equipment protection, and low operating costs.

Specifications & Ordering:

• Material: Laser-grade Fused Silica / Optical Glass

• Coating: Dual-side Anti-Reflection (AR) Coating for common laser wavelengths (e.g., 1064nm)

• Diameter & Thickness: Available in standard and custom sizes to fit your specific lens holder.

• Surface Quality: High precision, optimized for laser applications.
