Description
The QBH Protective Lens is a high-precision optical protection window used in fiber laser cutting, welding, and cleaning machines equipped with a QBH laser connector. It acts as the first line of defense, protecting the internal optics and laser source from dust, smoke, metal spatter, and other contaminants generated during laser processing.
Manufactured from premium optical-grade fused quartz with a double-sided anti-reflective (AR) coating, the QBH Protective Lens provides exceptional laser transmission of up to 99.9%, minimizing power loss while ensuring excellent beam quality. Its superior thermal stability and high laser damage threshold make it ideal for continuous industrial applications.
Regular replacement of the QBH Protective Lens helps maintain consistent cutting and welding quality, reduces maintenance costs, and protects expensive laser source components from damage. It is compatible with most fiber laser systems, including MAX, Raycus, JPT, BWT, and RECI laser sources using a standard QBH connector.
