Abstract: A device for mapping the topography of the cornea (38) of an eye has a light source (10) for directing a beam of collimated monochromatic light characterized by a flat wave front onto the cornea. Positioned between the light source and the cornea is an objective lens (32) for focusing this flat wave front toward the cornea as a converging spherical wave front. The light reflected from the cornea passes back through the objective lens to establish a reflected wave front having deviations from the flat wave front caused by aberrations on the cornea that are indicative of corneal topography. This reflected wave front is then segmentally focused by a lens array (64) into a pattern which reveals the deviations for use in mapping the topography of the cornea.

Abstract: A wall structure for insulating the exterior surface of a high voltage coil having Roebeled windings is provided that comprises an inner insulating layer formed from a hardenable epoxy material for surrounding the coil and filling void spaces on the surface of the coil created by the Roebeled windings, a ground wall layer surrounding the inner layer for grounding the wall structure, and a semiconductive layer formed from a carbon filled epoxy material integrally molded around the outer surface of the inner insulating layer for reducing the electric stress across the insulating layer and in particular across any voids remaining after the insulative layer has been applied over the Roebeled windings on the exterior of the coil. The improved wall structure advantageously increases the lifespan of high voltage coils by reducing the electric stress across the inner molding layer, thereby reducing the probability that damaging electric arcing will ever occur in any void spaces present in this layer.
