Abstract
Methods and systems are provided for ultra-violet curing, and in particular, for ultra-violet curing of optical fiber surface coatings. In one example, a curing device includes a first elliptic cylindrical reflector, with a second elliptic cylindrical reflector housed within the first elliptic cylindrical reflector. The first elliptic cylindrical reflector and second elliptic cylindrical reflector have a co-located focus, and a workpiece to be cured by the curing device may be arranged at the co-located focus.
Claims6
A method, comprising:
- positioning a workpiece along a major axis of a first elliptic cylindrical reflector and a coaxial major axis of a second elliptic cylindrical reflector, the second elliptic cylindrical reflector nested within the first elliptic cylindrical reflector;
- positioning a light source within an interior of the first elliptic cylindrical reflector and the second elliptic cylindrical reflector;
- and
- emitting light from the light source, wherein the emitted light is reflected onto the workpiece by reflective surfaces of the second elliptic cylindrical reflector and by reflective surfaces of the first elliptic cylindrical reflector through an opening of the second elliptic cylindrical reflector.
