Abstract: An optical ferrule includes at least one light affecting element configured to affect one or more characteristics of light from an optical waveguide as the light propagates in the optical ferrule, the light affecting element having an input surface. At least one receiving element receives and secures the optical wave guide to the ferrule so that an output surface of the waveguide is optically coupled to the input surface of the light affecting element. A waveguide stop limits movement of the wave guide toward the input surface of the light affecting element when the optical waveguide is installed in the receiving element. A space between the output surface of the optical waveguide and the input surface of the light affecting element is inaccessible to the optical waveguide when the optical waveguide is installed in the receiving element.

Abstract: An optical connector assembly (100) includes a housing (110), an optical ferrule (140); and an optical fiber array (150). The housing (110) has a mating end (111) and an opposite cable end (112) and includes: a first housing portion (120) including a front support (122) proximate the mating end (111) and a rear support (124) disposed between the front support (122) and the cable end (112); and a second housing portion (130) assembled to the first housing portion (120) and including a middle support (133) disposed between the front and rear supports (122,124). The ferrule (140) is supported by the front support (122). Front ends of optical fibers of the optical fiber array (150) are received by and attached to an attachment area of the ferrule (140). When the second housing portion (130) is assembled to the first housing portion (120), the middle support (133) of the second housing portion (130) contacts and bends the optical fiber array (150) about the middle support (133). The bend causes the optical ferrule (140) to rotate about the front support (122).

Abstract: An optical adaptor for inspection of a desired surface of an optical ferrule is provided. The optical ferrule is disposed in, and has a first position relative to, a housing of the optical ferrule. The optical adaptor includes a front portion including an open front end for insertion into the housing of the optical ferrule from an open mating end of the housing and for receiving at least a portion of the desired surface of the optical ferrule. The front portion includes a receiving surface for receiving at least a portion of the optical ferrule and causing the optical ferrule to change its position from the first position to a different second position. An image forming surface forms an image of the desired surface of the optical ferrule, thereby allowing a viewing of the optical ferrule from an open rear end of the optical adaptor.

Abstract: The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.

Abstract: An inspection device for an optical ferrule includes one or more reflectors. Each reflector has a mating surface and a mirror disposed at an oblique angle with respect to the mating surface. Each reflector is configured to mate with the optical ferrule when the optical ferrule is disposed within a housing of an optical connector. When the mating surface of the reflector is in mated contact with the mating surface of the optical ferrule, the mirror is positioned to provide a reflected view of at least a portion of a mating surface of the optical ferrule.

Abstract: Solar light redirecting glazing units include light redirecting and light diffusing constructions. The solar light redirecting glazing units may include a glazing substrate, a visible light diffusing layer, and a light redirecting layer oriented such that incoming solar light contacts the visible light diffusing layer before contacting the light redirecting layer. The solar light redirecting glazing units may include a glazing substrate, a patterned visible light diffusing layer, and a light redirecting layer. The solar light redirecting glazing units may include two glazing substrates separated by an intervening space with a solar light redirecting layer disposed on one glazing substrate, and a visible light diffusing layer disposed on the other glazing substrate.

Abstract: An optical ferrule comprises first and second compound stop features respectively disposed at opposing sides of the optical ferrule. Each compound stop feature has upper and lower contact surfaces. The lower contact surface is offset below the mating surface of the optical ferrule along a thickness axis perpendicular to the mating surface. The upper contact surface is offset above the mating surface along the thickness axis. The lower contact surface is offset forward from the upper stop surface along a mating direction of the optical ferrule. A connecting surface connects the upper contact surface and the lower contact surface.
