1. An optical fiber curing component, comprising:
a first tube comprising a first body defining a first interior surface and a first exterior surface, the first tube defining a first aperture and a second aperture on opposite ends of a first cavity, wherein the first tube defines a central axis extending through the first cavity;
a plurality of light sources coupled to the first body of the first tube and configured to emit light having a wavelength range from about 250 nm to about 410 nm toward the central axis of the first tube, wherein each of the light sources intersect a common plane defined perpendicular to the central axis of the first tube;
a silica glass article having an anti-reflective coating, wherein the silica glass article is disposed between each of the plurality of light sources and the central axis of the first tube; and
a reflective coating positioned on the interior surface of the first body and configured to reflect the light toward the central axis of the first tube.
