1. A method for assembling a plurality of optical fibers and a plurality of lenses in a support structure for an ablation catheter, the method comprising:
providing the support structure comprising a proximal end, a body, and a distal end, wherein the distal end comprises a plurality of alignment orifices;
threading the plurality of optical fibers through the plurality of alignment orifices at the distal end, wherein each optical fiber in the plurality of optical fibers is threaded through a corresponding alignment orifice in the plurality of alignment orifices;
applying an adhesive material to the plurality of optical fibers and to the distal end, such that the plurality of optical fibers are fixed in place in the support structure;
cleaving the plurality of optical fibers at the distal end to remove portions of the plurality of optical fibers extending out of the distal end of the support structure; and
attaching a lens to each end of the plurality of optical fibers, resulting in the plurality of lenses being attached to the ends of the plurality of optical fibers.
