Filed:

Nov 7, 2008

Appl. No.:

12/267380

Inventors:

Jonathan Michael Butler - Gainesville GA, US
Robert Troy Hewlett - Cumming GA, US
Robert Jeffrey Hewlett - Dawsonville GA, US
Robert McCoy Hewlett - Cumming GA, US

Assignee:

Endure Medical, Inc. - Cummings GA

International Classification:

F21V 33/00

US Classification:

362253, 362234, 362572, 359385, 359389

Abstract:

The invention is a novel stereoscopic illumination system for a microscope which delivers at least two collimated light beams to a subject surface. Each of the two collimated light beams is delivered for an eye of the user. Additionally, a third light beam is provided at an angle oblique to the other two collimated light beams.

International Classification:

F21V 33/00

US Classification:

362253, 362234, 362572, 359385, 359389

Abstract:

Systems and methods are provided for illuminating a surface to be observed microscopically using a retractable beamsplitter. The retractable beamsplitter allows the use of coaxial illumination when the beamsplitter is positioned in the operator's line of sight. The retractable beamsplitter allows the use of non-coaxial illumination without reducing the amount of illumination that reaches the operator when the beamsplitter is retracted from the operator's line of sight. As a result a single system can be used effectively to provide various types of illumination.

Appl. No.:

13/862792

Inventors:

Robert T. Hewlett - Cumming GA, US
Steven M. Frank - Suwanee GA, US

International Classification:

G02B 27/14

US Classification:

359629

Abstract:

According to certain embodiments, a system includes beamsplitter sets, where each beamsplitter set comprises a first beamsplitter module and a second beamsplitter module aligned with the first beamsplitter module. The first beamsplitter module receives a first beam traveling along a first optical path. The first beamsplitter module splits the first beam into a first output beam transmitted along the first optical path and a first split beam transmitted to the second beamsplitter module along a reflected beam path. The second beamsplitter module receives the first split beam. The second beamsplitter module splits the first split beam into a second output beam transmitted substantially parallel to the reflected beam path and a second split beam transmitted substantially perpendicular to the reflected beam path.

Filed:

Mar 23, 2018

Appl. No.:

15/934545

Inventors:

Robert Troy HEWLETT - Cumming GA, US
Jonathan Michael BUTLER - Gainesville GA, US

International Classification:

G02B 21/24
G02B 21/00

Abstract:

Disclosed is an attachment for a standalone optical device to alleviate back and neck strain which allows the eyes of the user relative to the eyepieces of the optical device, with embodiments allowing inclusion of preset values such as shape and dimension of the user's face, eye relief distance, pupillary distance. Eye relief may be optimized by the size and shape of the mask or by an adjustable eye relief mechanism. Movement of the eyes is achieved either by a mechanical pivot or by stretching of the mask being comprised of flexible material.
