Coating-grade fused silica protection window with single-side anti-reflection coating tuned for 1064 nm fiber lasers. Bevelled edge, λ/4 surface flatness, damage threshold above 15 J/cm². Engineered for Raytools, Precitec, WSX, and BOCI cutting heads.
This protection lens sits between the cutting head's focus optics and the laser beam exit. It is the first line of defence against back-reflection, spatter, and fumes — and the most consumed component on any fiber laser cutting line.
We manufacture from imported coating-grade fused silica with controlled internal stress, multi-stage polishing, and a precision-tuned AR coating for 1064 nm fiber lasers. Every batch is tested for damage threshold, transmittance, and surface quality before it leaves Taizhou.
Designed as a drop-in replacement for OEM consumables on Raytools BM114/BM115, Precitec ProCutter, WSX NC30/NC60, BOCI BLT, Bodor LC, and Han's Laser GH cutting heads.
Every batch is tested by an independent optical laboratory for transmittance, surface quality, damage threshold, and dimensional accuracy. Test reports are included with each order — no questions asked. Batch traceability via QR code on every ESD pouch.
Reports cover: transmittance curve (200–2000 nm), interferometer surface map, microscope inspection of coating, dimensional measurement against OEM spec, and accelerated-aging humidity test.
48-hour dispatch from Taizhou for in-stock SKUs. Regional warehouses in EU (Rotterdam) and US (Los Angeles) for buffer stock and faster local delivery.
DHL, FedEx, UPS, and sea-air combo options. Bonded warehouse arrangements available for distributors. We handle export documentation end-to-end including HS codes, certificates of origin, and CE/RoHS compliance docs.
