Abstract
Reticle apparatus that is affixed to the output surface of an image intensifier tube fiber optic element in a night vision goggle system. One embodiment provides for an illuminated reticle pattern. The reticle pattern is etched into a glass substrate which is then filled by a light reflective material. At least one light emitting diode (LED) is positioned adjacent to the edge of the substrate. Light from the LED is then received by the edge of the substrate which then illuminates the reticle pattern. An alternate embodiment provides for a reticle pattern that is affixed to an output surface of a fiber optic element wherein the output surface is curved. The reticle pattern is formed on a clear, flexible substrate that is able to conform the curvature of the output surface. The substrate is affixed to curved output surface by an adhesive that is coated on the flexible substrate.
