Abstract

A device for coating a fiber includes a fiber receiving arrangement and a coating arrangement which includes an application unit which wets the fiber with a coating agent, and a curing unit arranged downstream of the application unit which optically cures the coating agent. The curing unit includes a lamp which emits at least one light beam which is aimed directly or indirectly at a surface of the fiber. A main radiation direction of the lamp includes a beam angle between the main radiation direction and a longitudinal direction of the fiber of less than 40°. The fiber receiving arrangement and the application unit are movable relative to each other in the longitudinal direction of the fiber via a translational motion arrangement so that a wetting process is implemented substantially along an entire length of the fiber.
