Laser Cutting Machine Protective Lens D36*T5mm
Ø36 mm × 5 mm fiber laser protective window lens — a precision optical shield placed at the laser head’s output to block spatter and debris while preserving cutting beam quality and energy transmission.
Key Features
• High-transmission AR coating — maintains efficient beam throughput with low losses.
• Robust fused silica substrate — resists thermal stress and high power exposure.
• Optimal thickness balance — 5 mm thickness offers durability without excessive beam distortion.
• Contamination resistance — reduces buildup, extending service intervals.
• Precision flatness — supports repeatable focus and cutting consistency.
Applications
Engineered for industrial fiber laser cutting systems to protect internal optics, reduce downtime, and sustain stable cutting quality on metals.
Compatible Cutting Heads
Compatible with Bystronic/Nukon and similar fiber laser cutting heads that use Ø36 mm × 5 mm protective windows (non-OEM or aftermarket).
