US Patent:

56335040, May 27, 1997

Filed:

Mar 30, 1995

Appl. No.:

8/413327

Inventors:

Theresa A. Collins - Park Ridge IL
L. Lawrence Chapoy - Barrington IL

Assignee:

Wesley-Jessen Corporation - Chicago IL

International Classification:

G01N 2164

US Classification:

2504611

Abstract:

A system and method for inspecting an optical component such as a hydrated contact lens in which the system includes an illuminator providing light to a receptacle supporting the optical component with a saline solution and an imaging sensing device such as an eye or a video camera detecting fluorescent light generated in the optical component or in some portion of the receptacle and blocked by the optical component. The system and method are particularly useful for inspecting optical components which have been produced to have ultraviolet-absorbing properties.

Filed:

Aug 16, 1994

Appl. No.:

8/291219

Inventors:

Theresa A. Collins - Park Ridge IL

Assignee:

Wesley-Jessen Corporation - Des Plaines IL

International Classification:

G01B 1506

US Classification:

378 58

Abstract:

A system is provided for inspecting components, especially plastic components such as contact lens casting cup assemblies. A process for inspecting such components is also provided. The process comprises transmitting x-rays through the object to be inspected and then onto an image sensing means.
