Optical Article Having A Conductive Anti-Reflection Coating

US Patent:
4422721, Dec 27, 1983
Filed:
Aug 9, 1982
Appl. No.:
6/406302
Inventors:
Robert E. Hahn - Santa Rosa CA
Thomas R. Jones - Santa Rosa CA
Peter H. Berning - Sebastopol CA
Assignee:
Optical Coating Laboratory, Inc. - Santa Rosa CA
International Classification:
G02B 110
US Classification:
350164
Abstract:
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.

Conductive Anti-Reflection Coating

US Patent:
7283303, Oct 16, 2007
Filed:
Jul 29, 2004
Appl. No.:
10/901696
Inventors:
Kazuaki Takano - Santa Rosa CA, US
Andrew John Church - Santa Rosa CA, US
Thomas R. Jones - Santa Rosa CA, US
Brad Scott Tarter - Santa Rosa CA, US
Assignee:
JDS Uniphase Corporation - Milpitas CA
International Classification:
G02B 1/10
US Classification:
359582, 359585, 359587
Abstract:
A conductive anti-reflection coating has a surface quarterwave layer that is broken up into smaller portions by inserting one or more thin layers of conductive material in the dielectric material. The resulting stack of alternating layers of a dielectric material and an electrically conductive material provides a solid electrical contact to the buried conductive layer and exhibits a low surface contact resistance.
