Abstract
A device for UV curing a coating or printed ink on a workpiece such as an optical fiber comprises at least two UV light sources equally spaced around a central axis, each UV light source comprising a reflector and a cylindrical lens, and the UV curing device configured to receive a workpiece along the central axis. The reflectors are configured to substantially reduce the emitting angle of light from the UV light sources, thereby directing the light substantially through the cylindrical lenses, the cylindrical lenses focusing the light intensely along a surface of the workpiece.
