The 120BT0300Z is a premium, high-precision collimation lens assembly engineered explicitly for RayTools industrial fiber laser cutting and welding heads. This OEM-quality optical unit is critical for transforming divergent light from the fiber cable into a perfectly parallel (collimated) beam, ensuring flawless focus stability and maximum processing accuracy.

Manufactured using ultra-pure imported fused silica and treated with advanced multi-layer anti-reflective (AR) coatings, the 120BT0300Z assembly features an exceptionally high laser damage threshold and excellent thermal stability, effectively eliminating focal shift during continuous high-power operations.
