BOCHU BOCI Original Laser Lower Protective Lens D34.0T5（8~60KW）

• High-purity fused silica substrate with exceptional thermal stability, engineered to withstand continuous cutting at 15kW without thermal shock cracking or fracturing.
• Dual-sided hard AR anti-reflective coating delivers 1064nm high light transmittance, minimizing laser energy loss and ensuring optimal cutting speed and edge quality.
• Strong coating adhesion resists metal spatter and allows light cleaning, reducing lens burn spots and lowering frequent replacement costs.
• Precision optical grinding with strict dimensional tolerances maintains coaxial light path stability, blocks molten slag, and protects internal focusing and collimating optics.
• Compatible with carbon steel, stainless steel, and aluminum sheet metal fabrication across thin and medium-thickness applications—a cost-effective consumable standard in industrial shops.
