High-Grade Corning Fused Silica and AR Coating
Crafted from premium Corning HPFS 7980 fused silica, this optical lens possesses an incredibly low thermal expansion coefficient and high resistance to thermal shock. Both surfaces are treated with an advanced double-sided anti-reflective coating (AR/AR @ 1064 nm), reducing energy loss from reflection to less than 0.2%, maximizing laser power transmission, and preventing thermal lensing effects.
Engineered for Extreme Industrial Conditions
Handheld laser welding creates significant amounts of heat, micro-spatter, and dust. The 3250010444 lens is manufactured with a hardened coating layer that resists surface scratches and dust adhesion, extending its overall service life and protecting the deeper fiber laser system mechanics from optical feedback damage.
Broad Compatibility with RayTools Systems
As an authentic replacement component, the 3250010444 lens perfectly integrates with the optical assembly of the RayTools BW101-GS laser welding torch series. Its absolute dimensional precision (20mm diameter and 4.5mm edge thickness) ensures seamless fitment inside the lens holder, eliminating beam deviation and maintaining a consistent weld bead quality.
