Reflector for curing optical fibers and methods of using the same

An apparatus for curing a coating composition disposed on a glass optical fiber, the apparatus comprising:

• a reflector having a longitudinal length and defining a cavity, the reflector comprising:
• an interior surface delineating a boundary of the cavity, the interior surface comprising:
• a first portion extending along a first curved contour, the first curved contour forming a first circle comprising a first radius and a first center disposed at a first center location within the cavity;
• a second portion extending along a second curved contour, the second curved contour forming a second circle comprising a second radius and a second center disposed at a second center location within the cavity;
• and
• a third portion extending along a third curved contour, the third curved contour forming a third circle comprising a third radius and a third center disposed at a third center location within the cavity,
• wherein a fiber location for the glass optical fiber is displaced from the first, second, and third center locations.
