Laser Cutting Machine Protective Lens D24.9×1.5mm
Protective lens D24.9×1.5 mm for fiber-laser cutting heads. Fused-silica design with high transmittance and stable performance for continuous industrial metal cutting. Built for long-life protection in high-power laser environments.
Features
- High-purity fused-silica substrate with low absorption and strong heat resistance.
- Double-sided anti-reflection coating for reduced loss and stable beam energy.
- Precision-polished surface for minimal scattering and consistent cutting quality.
- Anti-spatter durability for stainless steel, carbon steel, aluminum, and galvanized cutting.
- Accurate dimensions ensure reliable sealing in mainstream laser-head structures.
Advantages
- Extends focusing and collimating lens lifetime.
- Reduces downtime caused by contamination and overheating.
- Maintains beam stability for smoother edges and reduced burr.
- Supports long-cycle high-power cutting from 1 kW to 20 kW.
- Low consumable cost for continuous factory-level operation.
Protective Lens Applications
Suitable for sheet-metal cutting, tube-cutting machines, automation lines, and OEM manufacturing systems. Protects the optical path during high-speed cutting of carbon steel, stainless steel, aluminum alloy, brass, and coated metals.
