A magnetron sputtering cathode for use in a vacuum deposition process is disclosed wherein the cathode is coated on its sides with an electrically insulating material such as alumina to prevent arcing, and wherein the first end surface of the cathode supports a material to be sputtered. The bottom of the cathode may also be coated with an electrically insulating coating or may be resting upon an insulating platform.

Cathode for sputter coating

Flexible selective energy control sheet construction formed of a sheet of substantially transparent polymer thin film plastic material having first and second surfaces. A substantially transparent continuous adhesion promoting layer is adherent to the second surface of the sheet. A substantially transparent metal layer is adherent to the adhesion promoting layer and a protective layer is adherent to the metal layer. The metal layer is selected from the materials of copper and silver.

Optical article having a substrate with first and second surfaces and with a conductive antireflection coating disposed on the first surface. The conductive antireflection coating is comprised of at least one layer of a low index material carried by said first surface and a thin transparent conducting layer of a material having a high index of refraction carried by the layer of material having a low index of refraction. The conducting layer provides an exposed surface to which the direct electrical contact can be made. The conducting layer has an optical thickness ranging from 1.0 to 30.0 nanometers. The layer of material having a low index of refraction has its design thickness reduced to compensate for the thickness of the conducting layer whereby the conducting layer does not seriously degrade the optical performance of the coating over that which could be obtained without the use of the conducting layer.
