The 3250010352 is an OEM original, high-precision biconvex spherical focusing lens engineered specifically for RayTools professional high-power fiber laser cutting heads. Operating at a standard fiber laser wavelength of 1064nm, this optical component is optimized for heavy-duty industrial systems rated up to 6.0 kW (commonly utilized in RayTools BM06K and BS06K series). Its primary function is to work in tandem with a matching meniscus lens to tightly converge the incoming parallel laser beam into a flawless, minimum-diameter focal point to deliver ultimate processing speeds and razor-sharp edge quality.

Crafted from ultra-pure, high-transmittance Premium Quartz Fused Silica, the lens features an exceptionally high laser damage threshold and excellent mechanical durability. Both sides are treated with advanced, multi-layer anti-reflective (AR) coatings to minimize power absorption and ensure maximum light transmission. This superior thermal stability effectively eliminates focal shift, guaranteeing perfectly stable cutting paths and consistent processing quality during extended industrial workloads at multi-kilowatt power levels.
