Night sight for a missile launcher comprising an image intensifier tube, a reticle, and an objective lens

摘要

A night sight for a missile launcher has an objective lens with a field of view of at least 22 degrees. The output image of the objective lens is intensified by a variable gain light intensifier tube and the output of the intensifier is viewed through an eyepiece. A reticle pattern etched on a glass substrate and filled with titanium dioxide is illuminated by adjustable brightness LED's positioned at points on the periphery of the substrate. The reticle is disposed between the light intensifier and the eyepiece and substantially duplicates the function of reticles used in daysights.
