1. Apparatus for treating material with concentrated radiant energy comprising:
- (a) first and second reflectors comprising an elliptical reflector having a source focus and an object focus;
(b) a volume radiant energy source positioned at said source focus;
(c) means for positioning material to be treated with radiant energy at said object focus; and
,(d) an auxiliary reflector having a concave reflecting surface, said auxiliary reflector being positioned near said object focus and having its concave surface facing both foci of the elliptical reflector so as to direct towards said object focus at least a portion of the radiation which originates at said source and strikes the auxiliary reflector.

Abstract
Apparatus for treating material with radiant energy, especially adapted for curing photocurable polymeric materials coated onto an optic fiber. The apparatus includes first and second reflectors which in combination form an elliptical reflector, a light source positioned at one focus of the elliptical reflector and a photocurable polymer-coated wire-like material or a fiber such as an optical fiber positioned at the second focus. An auxiliary reflector is located near the second focus in such a position as to direct light rays impinging thereon towards the second focus, thus increasing the amount of energy which impinges on the polymer coating.
