Fiber drawing tower
Laserentis, a holographic optical computing technology, inspects all fiber layers simultaneously and detects subtle drawing process deficiencies and inconsistencies. The system detects air bubbles, embedded particles and debris, blowouts, abrasions and delamination. The tower also inspects hermetic coating for pinholes, uneven coating thickness and coating delamination. The Microentis measures all fiber-layer dimension, noncircularity, primary buffer/cladding concentricity and secondary/primary buffer concentricity.
