Laser Cutting Machine Protective Lens D27.9×4.1mm

Key Features

1. High-Purity Fused Silica Material
   Built with low-absorption fused silica to maintain excellent beam transmission. Ensures minimal optical loss and stable performance during long cutting cycles.

2. Dual Anti-Reflection Coating (AR Coating)
   Both surfaces feature precision AR coatings that reduce reflectivity, improve transmittance, and enhance cutting efficiency even under 6–30 kW power levels.

3. High Temperature and Spatter Resistance
   Coating structure is optimized for thermal shock resistance, preventing film cracking or discoloration during high-speed metal cutting applications.

4. Scratch-Resistant Surface Treatment
   Durable surface enhances resistance to handling damage, contamination, and cleaning abrasion, extending lens service life and lowering maintenance costs.

5. Precision Dimensions for Stable Installation
   Strict tolerance control ensures perfect compatibility with standard protective lens holders, providing airtight sealing against dust and fumes.
