An optical device includes a housing enclosure, a lens cell holder mounted to the housing enclosure by a retainer, a lens assembly mounted to the lens cell holder such that the lens assembly is configured to translate in an axial direction; and a radial space defined between the lens cell holder and the retainer that is sized to accommodate adjustment of the lens cell holder and the lens assembly in a radial direction with respect to the housing enclosure. A method of adjusting a line of sight of the optical device includes (i) positioning the lens assembly against the housing enclosure; (ii) adjusting the radial position of the lens assembly until a pre-determined line of sight requirement is achieved; and (iii) fixing the lens assembly to the housing enclosure of the optical device to preserve the radial position of the lens assembly with respect to the housing enclosure.

Translational optic alignment locking device

A night vision goggle system includes a housing, and an eyepiece forming a back end of the housing for viewing an object of interest. An optical field-of-view (FOV) is formed through the eyepiece, where the FOV is defined by a cone having an apex formed adjacent to an exit pupil at the eyepiece and tapering outwardly toward the object of interest. A desiccant is disposed within the housing, and located outside the FOV. The desiccant is visible through the eyepiece when viewed from outside the FOV. In addition, when the eye of a user is placed within the FOV, the desiccant is not visible through the eyepiece; and when the eye of the user is placed outside the FOV, the desiccant is visible through the eyepiece.

A night vision device is disclosed. The device includes a housing that houses an intensifier tube and a proximity sensor mounted on the housing. An ON/OFF switch is operatively coupled to the intensifier tube and to the proximity sensor such that operation of the ON/OFF switch to the 'ON' position automatically activates the proximity sensor. A method of operating the night vision device with the proximity sensor is also disclosed.

A night vision device includes an image intensifier tube and a fiber optic screen disposed in operative relationship to each other. The fiber optic screen includes a longitudinal bundle of multiple optical fibers, where the bundle has an outer surface. A groove is formed in the fiber optic screen and extends transversely to the longitudinal bundle. An indicator is positioned adjacent to the outer surface of the bundle and is proximate to the groove, where the groove is configured to redirect light emitted from the indicator for viewing by a user. The groove may be formed circumferentially around a portion of the outer surface of the longitudinal bundle. The groove includes a surface of end portions of multiple cut optical fibers, and the groove is configured to redirect the light emitted from the indicator toward the user by way of the end portions of the multiple cut optical fibers.

A night vision device comprising a first detector, a beam splitter, a user optical output and a camera. The first detector is configured to detect and transmit a scene image in a first spectral band along a first optical path. The beam splitter is configured to receive the first optical path image; to output, along a second optical path, a first portion of the first optical path image, and to output, along a third optical path, a second portion of the first optical path image. The user optical output is configured to receive and output images traveling along the second optical path. The camera is configured to receive and store images traveling along the third optical path.

Night vision goggle with separate camera and user output paths

The present invention provides a mega-boule for use in fabricating microchannel plates (MCPs). The mega-boule includes a cross-sectional surface having at least first, second and third areas, each area occupying a distinct portion of the cross-sectional surface. The first and second areas include a plurality of optical fibers, transversely oriented to the cross-sectional surface, each optical fiber having a cladding formed of non-etchable material and a core formed of etchable material. The third area is disposed interstitially between and surrounding the first and second areas, and includes non-etchable material.
