High-purity fused silica material ensures superior UV to IR light transmission (190nm-2500nm) with 99.9% optical clarity. Precision-polished surfaces achieve λ/10 flatness and 10-5 scratch-dig standards for distortion-free laser beam delivery.

Hard-coated anti-reflective treatment minimizes surface reflection to <0.5% at 1064nm, boosting laser system efficiency. Withstands 10J/cm² pulsed laser damage threshold (1064nm, 10ns) for industrial-grade durability.

CNC-machined aluminum alloy frame features military-grade anodization, maintaining dimensional stability under 500°C thermal shock. Integrated O-ring groove design enables hermetic sealing for vacuum chamber applications.

Essential for fiber laser engraving/cutting systems, medical laser devices, semiconductor lithography equipment, and aerospace laser measurement tools. OEM bulk quantities available with custom AR coatings upon request.
