Max QBH Protective Lens / Protective Window Cap
Professional dedicated protective window lens matched for Max fiber laser sources. Standard outer diameter D12.8mm with three optional heights: H16.8, H18.5 and H19.8. This optical protective cap effectively shields core internal components of laser sources, while maintaining stable and efficient laser energy transmission for long-term high-power laser operation.
Key Product Features
-
99.7% Ultra-high Laser Transmittance: Supports 1064nm and 1080nm mainstream fiber laser wavelengths with light transmittance ≥99.7%, realizing lossless laser energy output and no reduction in cutting/welding power.
-
Superb Heat Resistance: Adopts high-end optical glass with extremely low thermal expansion coefficient. It can sustain continuous high heat generated by high-power lasers, preventing lens cracking, deformation and thermal drift.
-
Double-sided Multi-layer AR Coating: Premium anti-reflection coating on both lens surfaces greatly reduces laser reflection loss, improves laser utilization rate and ensures consistent laser beam quality.
-
Original Standard Size: Exact OEM dimension fits Max QBH laser port perfectly, plug-and-play installation, no extra calibration required after replacement.
