ZNK Converging Lens D30-F100 Composite — Raytools Type
This converging (focusing) lens is a precision optical consumable for fiber laser cutting heads. It is a composite design combining a double-convex and a crescent-shaped element to focus the laser beam onto the workpiece. Made from high-purity fused silica, the Ø30 mm diameter and 100 mm focal length are fixed by the model designation, and the part is an original Raytools item.
