Patent attributes
An apparatus for curing a coating composition disposed on a glass fiber includes a diffuse reflector surrounding a coating composition disposed on a glass fiber. The diffuse reflector defines a cavity having a sidewall extending from a first end to a second end. The first end has a first opening and the second end has a second opening. The glass fiber passes through the cavity from the first opening to the second opening. The sidewall has an interior surface facing the coating composition disposed on the glass fiber. The interior surface includes a scattering material. A light source integrated with the diffuse reflector. The light source directs light to the scattering material. The scattering material diffusely reflects at least 90% of the light. The diffusely reflected light has sufficient intensity to cure the coating composition.
