Electro-Optics is the pioneer of Glass Coated Wire technology,
originally developed to improve the electrical characteristics
of ion-generating corona wires in high speed copiers. An
insulating layer of glass can be added to nearly any kind
of metal wire by drawing the wire through a molten glass
preform. The glass is chemically bonded to the wire and
hermetically sealed, protecting the wire from oxidation
and chemical attack.
