The 3250010305 is an original, high-precision collimation lens engineered specifically for RayTools fiber laser cutting and welding heads. Operating at a standard fiber laser wavelength of 1064nm, this optical component is optimized for medium-to-high power systems rated up to 4kW. Its primary function is to accurately shape and straighten the divergent laser beam exiting the fiber cable before it reaches the focusing optics.

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.
