Laser Machine Consumables
Protective Lens
for Fiber Laser
Machines
Reliable replacement protective lenses for laser cutting and welding systems. Multiple size options cover low-power to high-power machines, with common consumables supported through MetalBaja's U.S. local service workflow.
Keep Your Laser Head Protected and Production Moving
Protective lenses are small consumables, but they play a critical role in keeping the optical path clean. The right lens helps shield the laser head from spatter, smoke, dust, and daily workshop contamination.
Protect Critical Optics
Use the protective lens as the first consumable barrier before contamination reaches more expensive optical components inside the laser head.
Match Size and Power
Choose from multiple diameter and thickness combinations for 3kW, 12kW, 20kW, and 30kW laser power ranges.
Fast Replacement Support
MetalBaja supports key wear parts and consumables through its U.S. service and parts workflow, helping reduce unnecessary downtime.
Built for Fiber Laser Cutting and Welding Workflows
Whether you are replacing a lens during routine maintenance or preparing spare parts for production, the selection should match the machine power, cutting head or welding head model, and original lens dimensions.
- Available for common low-power and high-power fiber laser machine configurations.
- Useful as scheduled spare parts for workshops running daily cutting or welding jobs.
- MetalBaja can help confirm the right lens size before quotation when you provide your machine model and current lens dimensions.
