Fiber Laser Cutting & Welding Equipment Protective Lenses

Fiber Laser Cutting & Welding Equipment Protective Lenses

Material Selection:

     Utilizes premium fused silica (Corning 7980, OHARA, JGS1) for fiber laser cutting heads >12kW. Ensures excellent high-temperature resistance, laser damage resistance, and optical transmittance.

     Adopts high-purity fused silica JGS2 and BK7 materials for low-power fiber laser & CO2 cutting/welding heads, marking machines, etc. Standard fused silica + AR coating offers cost-effective, efficient performance.

Partial Technical Parameters:

     Diameter Range:        Φ10mm–Φ210mm

     Thickness:                  1mm–12mm (customizable)

     Surface Accuracy:      λ/4 @ 632.8nm

     Damage Threshold:   >15 J/cm² (1064nm, 10ns pulse)

     Coating Process:       Double-sided antireflective (AR) coating 532/635/1064nm >99.8%. 

                                           Wavelength transmittance reaches 99.8% to reduce energy loss.

Core Protection Components for Laser Cutting/Welding Machines & Marking Devices:
     Laser Cutting:           Compatible with 0–30,000 W fiber laser cutters for metal/plastic/composite processing.
     Laser Welding:         Suitable for high-precision welding equipment in automotive/aerospace/electronics industries.
    Compatible Brands:  RayTools, Precitec, Trumpf, Bystronic, IPG, Han's Laser, etc.
    Other Applications:   Medical lasers, precision marking, 3D printing, etc.

Core Advantages

    Superior Durability:    Exceptional damage threshold performance for continuous high-power laser environments.
    Precision Optical Performance:    Low absorption and high transmittance ensure processing accuracy and stability.
    Flexible Customization:     Supports personalized design for dimensions, coatings, and materials.

I understand your hesitation at the moment. Perhaps you could consider
   Low-power (≤6kW):            Choose standard fused silica + AR coating for cost-effective efficiency.

   High-power (30KW>6kW): Recommended premium fused silica + AR coating for enhanced heat resistance.
   Harsh Environments:     Optional anti-fouling coating (DLC-like diamond coating) reduces slag adhesion.

This choice is indeed not easy. We can provide a small number of samples in stock.
