✅ Optimized for Thick Materials – 200mm focal length delivers better beam convergence for deeper penetration.
✅ Ready-to-Install Assembly – Complete with holder and seals for a seamless, tool-free swap.
✅ Restore Cutting Integrity – Regain square edges, consistent kerf, and optimal power density.

Signs Your BOCI Focusing Lens Needs Replacement

• Inability to Cut Through Thick Material despite correct settings
• Tapered or Wedge-Shaped Kerf on thick plates
• Poor Edge Quality (excessive dross, roughness) on deep cuts
• Reduced Peak Power Density at the workpiece
• Visible Damage on the lens center (pitting, coating burn)
• Frequent Need to Re-focus during jobs

If you're facing these issues, your focusing lens may be degraded. Using a damaged lens wastes power and compromises cut quality. Replace it with an original to restore your laser's capability.
