Abstract
A mount for handling and conveying optical material is disclosed. The mount includes an elastic band disposed around the circumference of the optical material and a hanger. The hanger includes an upper generally "T" shaped suspension portion and a lower engagement hook. The engagement hook slips between the elastic band and the surface of the optical material such that the material may be suspended and conveyed by the hanger. Where a thin edge plastic lens is to be conveyed which cannot support an elastic band disposed around its circumference, a small hole is provided near the edge of and through the lens. The engagement hook of the hanger is passed through the hole and the lens may then be conveyed by the hanger. An alternate embodiment is disclosed for use where only one side of a lens is to be coated.
