This invention discloses apparatus for processing one or more of a Lens Precursor, a Lens Precursor Form and an ophthalmic Lens. The guiding catheter comprises an inner layer, a reinforcement layer, and an outer layer. The insulating and metallic layers are dimensioned so that a larger collection cell can be used to collect solar energy over a larger proportion of the available substrate surface area, without causing arcing between the cell edge and the metallic layer edge.
