  • Process for the production of a reflection-reducing coating on lenses
    Patent number: 5597622
    Abstract: The invention relates to a process of providing a scratch-resistant coating for a lens made of an optical material comprising synthetics. In order for the synthetic material, for example a CR 39, to be protected against scratches, a very thin adhesion layer of SiO is applied first, and is subsequently provided with a thick SiO.sub.2 layer. Both layers are deposited in a vacuum chamber which comprises both a thermal vaporizer for vaporizing the coating materials and a plasma source for irradiating the substrate simultaneously with application of the vaporized coating material.
