Title: Method for curing a photocurable coating provided on a fiber

Abstract: An apparatus for curing a photocurable coating provided on a fiber, includes an irradiator tube having an upstream end on which an injection assembly is provided, and a downstream end on which an exhaust assembly is provided. The injection assembly receives an inert gas flow. The injection assembly includes a diffuser that splits the inert gas flow into a counter flow and a tube flow. The counter flow is directed counter to the travel direction of the fiber, and the tube flow is directed in a laminar fashion through the irradiator tube. The exhaust assembly has a vent though which the tube flow is drawn, and an air opening provided between a downstream end of the irradiator tube and the exhaust vent.
