Power Delivery Preforms (UV / IR)Power Delivery Preforms (UV / IR)
Our UV fused silica rod is free from inclusions and bubbles and performs reliably. It offers the best laser durability, refractive index homogeneity and stability under thermal conditions and stress. The rod is highly homogeneous and shows no striations along its functional length. Typical applications are optical elements such as lenses, windows, wafers and optical fibers.
