Patent number: 10649210Abstract: A display apparatus has an image generator that generates image-bearing light from a f surface and a lens spaced apart from the image generator and having an aspheric incident refractive surface concave to the image generator and having an aspheric reflective surface concave to the image generator, wherein a principal axis of the reflective surface is normal to the image generator. A beam splitter plate disposed in free space between the image generator and the lens has first and second parallel surfaces that are oblique to a line of sight of a viewer. The lens and the beam splitter plate define a viewer eye box for the image-bearing light along the line of sight of the viewer.Type: GrantFiled: January 20, 2017Date of Patent: May 12, 2020Assignee: Corning IncorporatedInventors: Joshua Monroe Cobb, Kevin J Magierski

Patent number: 9557516Abstract: An optical system includes a lens assembly and a light source. The lens assembly includes an optical lens positioned to transmit and refract light provided by the light source, and a lens holder coupled to the optical lens and maintaining a position of the optical lens relative to the light source. The optical lens is coupled to the lens holder with a bonding agent arranged in an interrupted configuration at positions proximate to a circumference of the optical lens. The light source provides light to the optical lens of the lens assembly that has an optical footprint that includes a plurality of high-intensity regions separated from one another by low-intensity regions and the bonding agent is positioned in a circumferential orientation relative to the light source such that the bonding agent is spaced apart from the high-intensity regions of the optical footprint of the light.Type: GrantFiled: October 7, 2013Date of Patent: January 31, 2017Assignee: Corning IncorporatedInventors: Robert Dennis Grejda, Keith Ernest Hanford, Kevin J Magierski, Todd Robert McMichael

Publication number: 20140240859Abstract: An optic obscuration assembly, a system and method for working on an optical element, and the resulting optical element are described herein. In one example, the system and related components (e.g., optic obscuration assembly, positioning system, and coating system) allow the accurate placement of a very round thin metal obscuration (e.g., thin metal disk) in the center of a front surface of the optical element before a high reflective thin film coating is applied to the front surface. Once, the optical element has had the high reflective thin film coating applied thereto then the thin metal obscuration is removed to reveal a transmissive aperture.Type: ApplicationFiled: August 2, 2013Publication date: August 28, 2014Applicant: CORNING INCORPORATEDInventors: Glenn A. Parker, Kevin J. Magierski, Brian Monroe McMaster

Patent number: 7916408Abstract: An optical element mount has an inner member suspended within an outer member by a plurality of flexures. A first and a second translational adjustment apparatus are disposed to translate the inner member within a translation plane that is orthogonal to an optical axis, wherein each translational adjustment apparatus has an actuator movable within the outer member along a linear travel path that is parallel to the translation plane and a shaft extending between the outer and inner members, the shaft coupled to the actuator with a first ball-and-socket joint and coupled to the inner member with a second ball-and-socket joint. The linear travel path of the actuator for the first translational adjustment apparatus is substantially orthogonal to the linear travel path of the actuator for the second translational adjustment apparatus.Type: GrantFiled: October 30, 2008Date of Patent: March 29, 2011Assignee: Corning IncorporatedInventors: Douglass L Blanding, Jack W Frankovich, Keith E Hanford, Kevin J Magierski

Patent number: 7612956Abstract: An optical element mount has an outer member and an inner member. The inner member has a central axis and is suspended within the outer member by a plurality of fold flexures. Each fold flexure has a fold that lies along a line that intersects the central axis at one common point, where the common point serves as a pivot point for rotational movement of the inner member.Type: GrantFiled: February 27, 2008Date of Patent: November 3, 2009Assignee: Corning IncorporatedInventors: Douglass L Blanding, John H Bruning, Jack W Frankovich, Keith E Hanford, Kevin J Magierski, Mark C Sanson
