8333474, Dec 18, 2012

Filed:

Sep 9, 2008

Appl. No.:

12/206974

Inventors:

Richard J. Michaels - Irvine CA, US
Max Hall - Corona CA, US
Diego Cueto - Monarch Beach CA, US
T. Scott Rowe - Dana Point CA, US
Thomas Padrick - Seattle WA, US

Assignee:

WaveTec Vision Systems, Inc. - Aliso Viejo CA

International Classification:

A61B 3/14

US Classification:

351208, 351246, 351205

Abstract:

An ophthalmic apparatus for precisely positioning an optical instrument, such as a wavefront aberrometer, in three dimensions with respect to a patient's eye. The ophthalmic apparatus may include an optical instrument directed in a first direction toward a target area to receive light therefrom and a camera directed in a second direction toward the target area to receive light therefrom, the first and second directions being non-parallel. The camera may include imaging optics to form an optical image on a photodetector array using light reflected from the target area. The ophthalmic apparatus may also include a processor configured to correlate a position of the optical image on the photodetector array with the distance between the optical instrument and the target area.

Filed:

Oct 9, 1997

Appl. No.:

8/947740

Inventors:

Richard J. Michaels - Irvine CA

Assignee:

Imagyn Medical Technologies, Inc. - Irvine CA

International Classification:

G02B 2102

US Classification:

359661

Abstract:

Objective lenses for endoscopes are made substantially of sapphire. The high refractive index of sapphire results in optical components with shallower curvatures, leading to smaller geometric aberrations, and consequently, fewer components are required to correct for these aberrations. Chromatic aberrations are less severe because of sapphire's low dispersion. The objectives may be either of the landscape or retrofocus type, and are compact with moderate field of view, low f-number, and less distortion than most conventional designs.

Abstract:

An adapter system for displaying and recording stereoscopic images from a single lens optic device and methods of producing stereoscopic images using such an adapter are provided herein. The adapter system utilizes an active stereoscopic shutter mounted along the optical path of the single lens optic device, such as, for example, a microscope or an endoscope, to provide a stereoscopic image to a video or still camera mounted along the same optical path.
