The 3250010353 is an OEM original, high-precision meniscus 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 biconvex lens to tightly converge the incoming parallel laser beam into a flawless, minimum-diameter focal point, significantly minimizing spherical aberrations to deliver ultimate processing speeds and razor-sharp edge quality.

Crafted from ultra-pure, high-transmittance JGS1 Quartz Fused Silica, the lens features an exceptional 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.
