Filed:

Mar 17, 2004

Appl. No.:

10/802172

Inventors:

Agnes Jallouli - Largo FL, US
Gerald Fournand - Tampa FL, US
James Reed - Clearwater FL, US
Danne Wright - Saint Petersburg FL, US

Assignee:

Essilor International Compagnie Generale d'Optique - Charenton cedex

International Classification:

B05D005/06
C23C016/00

US Classification:

427169000, 427162000, 11872300R

Abstract:

The process comprises the steps of: (a) subjecting said at least one main face of an optical lens to a corona discharge or atmospheric plasma treatment; (b) dipping the optical lens in a curable coating composition to deposit a layer of the curable coating composition on said main face; and (c) curing the curable coating composition layer; wherein during the whole process the optical lens is carried by a same lens holder so that the said lens face is freely accessible and without necessitating manual handling of the lens.

US Classification:

359742, 427558, 427164

Abstract:

The present method for coating a Fresnel lens blank includes providing an uncoated Fresnel lens blank having a structure surface and a non-structured surface, providing a transparent mold part having molding surface substantially matching the base curvature of the Fresnel lens, depositing a metered quantity of coating resin between the molding surface and the structured surface of the Fresnel lens, applying pressure between the Fresnel lens and the mold part while maintaining the distance between the molding surface and the structure surface so that the thickness of the coating is greater than 1.5 times the Fresnel structural height of the structured surface and less than 5 times of the Fresnel structure height of the structured surface and curing the resin coating in situ by directing the incident UV radiation at the Fresnel lens. A double coating may be employed for obtaining both higher optical power and better mechanical properties.

ESSILOR INTERNATIONAL (COMPAGNIE GENERALE D'OPTIQUE) - Charenton cedex

International Classification:

G02B 7/02

US Classification:

359811000

Abstract:

The invention relates to an optical lens holder () comprising a supporting means () and a first and a second arm () defining a lens holder general plane, first and second arms being relatively movable with regards to each other and each arm having spaced apart first and second end portions () and an intermediate portion (), the arms being mounted on the supporting means through their first end portions and the second end portions of each arm comprising an optical lens accommodating means () facing each other, whereby an optical lens () can be maintained within the accommodating means of the first and second arms with its optical axis orthogonal to the general plane of the lens holder through at least one, preferably one or two contact points between the lens periphery and each of the first and second lens accommodating means, wherein at least the second end portion of each arm comprises a material having a dielectric constant at 1 MHz equal to or higher than the dielectric constant of the optical lens material.
