Laser Cutting Machine Protective Lens D38*T9.8mm
Protective window lens Ø38 mm × 9.8 mm for fiber laser cutting machines. A precision optical shield that prevents spatter and debris from damaging internal focusing optics while maintaining high transmission of the cutting beam.
Key Features
• High transmission AR coating — ensures efficient laser energy throughput with minimal loss.
• Thick, rugged profile — 9.8 mm thickness enhances resistance to high-power laser and thermal stress.
• Fused silica substrate — low absorption and excellent optical clarity under industrial cutting conditions.
• Scratch-resistant surface — durable under frequent handling and maintenance.
• Stable focus performance — supports consistent cut quality and reduces beam distortion.
Applications
Used in industrial fiber laser cutting systems to protect optics and maintain stable high-precision cutting performance across metals.
Compatible Cutting Heads
Commonly applied in cutting heads that use 38 mm series protective windows, especially for 20 kW-class fiber laser heads; final compatibility should be confirmed with OEM documentation before ordering.
