Patent number: 8125718Abstract: A telescope that provides for simultaneous clear viewing of objects or areas at various distances may be either Galilean or astronomical. The telescope may be mounted on or into any mechanism or device used for targeting or aiming. Such devices may include iron sights of small arms weapons, and cameras and telescopes, which may be either electrically or manually focused. These miniature scopes are engineered to maximize the clear depth-of-field viewing by the eye regardless of vision irregularities, such as Presbyopia, Myopia, Hyperopic, Astigmatism, or combinations of these, in conjunction with or without spectacle lens corrections. This aiming scope/device may be placed on a pair of spectacles in a very close proximity to the eye cornea. Other maximized scope image characteristics that occur are field-of-view, luminosity, and unmagnified and unbroken or distorted viewing field.Type: GrantFiled: February 13, 2009Date of Patent: February 28, 2012Assignee: Edwards Optical CorporationInventor: D.

Patent number: 7911710Abstract: Miniature telescopes of both Galilean and astronomical design are fashioned to allow bi-level viewing, simultaneously, of both magnified scope images and non magnified normal images of both far and near objects or areas. Improvements in bi-leveling telescopes involve: objective lens aspherics, ocular lens materials of high refractive indices, anti-reflective fabric like materials for internal light control. This combination of innovations results in a bi-levelable miniature telemicroscope displaying wider magnified fields which display brighter and clearer imagery. Peripheral chromatic and spherical aberrations are considerably reduced even in shorter length telescope units. These shorter length scopes are spectacle mounted in such a way that the front surface of a spectacle carrier lens is coplanar with the telescope objective lens. Tintings and other coatings can now be applied to any of the scope's lenses or internal disks as well as to spectacle carrier lenses.Type: GrantFiled: September 17, 2007Date of Patent: March 22, 2011Assignee: Edwards Optical CorporationInventor: D.

Patent number: 5189560Abstract: Telescopes, both Galilean and astronomical, are mounted to small arms such as rifles, shotguns, pistols and bows. These telescopes are miniature in size mounted into the aiming mechanism of the small arm. The telescope imagery is engineered to produce simultaneous viewing of target and sight. Objects, including a barrel end post, at varying distances from the scope are all observed clearly, sharply and simultaneously on the image or exit pupil of the scope. This imagery may be enhanced with the use of glare control structures. Galilean scopes are herein described as being used with a reticle structure on the scope eyepiece or on, or beyond, the objective lens for calibrating/aiming guns and bows. The reticle figures are most accurately employed at eye relief distances of from near point (approximately 25 cm) to arms length (approximately 56 cm).Type: GrantFiled: February 15, 1991Date of Patent: February 23, 1993Assignee: Edwards Optical CorporationInventors: Bruce W.

Patent number: 5121251Abstract: A telemicroscope has a light absorbing and blocking annular baffle within the telemicroscope barrel. The baffle is positioned between the front and rear lenses and reduces glare in the telemicroscope by blocking and absorbing light which would ordinarily reflect off the inner surfaces of the telemicroscope barrel. The baffle has a knife-edge inner diameter and its surfaces are given a dull finish to enhance its light absorbing properties.Type: GrantFiled: February 4, 1991Date of Patent: June 9, 1992Assignee: Edwards Optical CorporationInventor: D.

Patent number: 5052790Abstract: To provide for bi-level viewing through a miniature Galilean telemicroscope, the telemicroscope is mounted to a carrier such that its optic axis is angled relative to a principal optic axis defined by the carrier. The carrier may be a spectacle lens, an adaptor to be pressure fit to the rear portion of the aiming mechanism or a gun, or an adaptor to be coupled to an optical instrument. The miniature scope may also be used as the principal sight aperture. Where the optical instrument is a larger telescope, an additional cross hair allows for alignment of the telemicroscope. Fibers extending inwardly from the inner surface of the telemicroscope barrel minimize internal light reflection. The telemicroscope barrel is formed of threaded-like coupled portions which may be rotated relative to each other for focusing.Type: GrantFiled: September 1, 1989Date of Patent: October 1, 1991Assignee: Edwards Optical CorporationInventors: D.
