Abstract
A curing apparatus utilizing ultraviolet radiation for curing a coating over the surface of a line-shaped medium such as an optical fiber, comprising: a pair of reflecting mirrors, each of which has an elliptical mirror surface, the ratio between the major and minor axes of which is within a range from 1.02 to 1.35; a source for producing ultraviolet radiation having a tube which is disposed along a first focal axis of the pair of reflecting mirrors for emitting ultraviolet radiation and has a diameter within a range from 12 mm to 24 mm and a light emission length equal to or longer than 15 cm; and an ultraviolet radiation transmission hollow tube which is disposed along a second focal axis of the pair of reflecting mirrors and through which the line shaped medium is passed in the axial direction of the hollow tube. The ultraviolet radiation emitting tube is air-cooled. The coating is cured in a stable and efficient manner, regardless of the thickness of the coating at a high or low transportation speed of the line-shaped medium.
