Publication number: 20040189981Abstract: A method and system for inspecting ophthalmic lenses using absorption where an ophthalmic lens is illuminated with light comprising wavelengths that are substantially absorptive to said lens, the image subsequently detected being created using only light at said absorptive wavelengths. Variations in transmitted light intensity translate into thickness changes in the lens caused by cosmetic flaws. The invention is also directed to imaging lens assemblies employing highly positive-powered field flattening lens elements to image a curved object, such as an ophthalmic lens, onto a flat image plane.Type: ApplicationFiled: March 31, 2003Publication date: September 30, 2004Inventors: Denwood F. Ross, Mary L. Dolan, Ranganath R. Raja, Brian G. Rice, Craig W. Walker, David Kappel, Robert E. Fischer, Ture Kindt-Larsen

Patent number: 5855104Abstract: An automated apparatus for controlling the automatic packaging of contact lenses in a contact lens fabrication facility includes: a first robotic transfer device for periodically transferring a first predetermined amount of individual packages from an inspection station to an intermediate consolidation buffer and depositing the packages on the consolidation buffer; a control device for tracking and identifying each individual contact lens conveyed from the inspection station to the consolidation buffer and including memory and logic circuits for storing the identity of individual packages containing contact lenses that have been previously determined at the inspection station as being out of specification, and, generating a signal to enable the first robotic device to discard any individual package identified as out of specification; and; a second robotic assembly for periodically transferring a second predetermined amount of individual packages from the consolidation buffer to a second processing station, thType: GrantFiled: March 3, 1997Date of Patent: January 5, 1999Assignee: Johnson & Johnson Vision Products, Inc.Inventors: Mark Schlagel, Russell J.

Patent number: 5500732Abstract: A system and method for inspecting ophthalmic lenses. The system comprises a transport subsystem for moving the lenses into an inspection position, and an illumination subsystem to generate a light beam and to direct the light beam through the lenses. The system further comprises an imaging subsystem to generate a set of signals representing selected portions of the light beam transmitted through the lenses, and a processing subsystem to process those signals according to a predetermined program. The illumination subsystem includes a light source to generate a light beam and a diffuser to form that light beam with a generally uniform intensity across the transverse cross section of the light beam. The illumination subsystem further includes a lens assembly to focus a portion of the light beam onto an image plane, and to focus a portion of the light beam onto a focal point in front of the image plane to form a diffuser background pattern on the image plane.Type: GrantFiled: June 10, 1994Date of Patent: March 19, 1996Assignee: Johnson & Johnson Vision Products, Inc.Inventors: James Ebel, Mary L. Dolan, Russell J. Edwards, Peter W. Sites
