Abstract
A lightweight night vision device that can be used by itself or can be selectively attached to either the objective lens assembly or ocular lens assembly of an existing optical device. The night vision device includes an image intensifier tube for amplifying low intensity light to produce a visible image. The image produced by the image intensifier tube is inverted. A prism assembly is positioned proximate to the image intensifier tube to reinvert the image in a space and cost efficient manner. The image intensifier tube, the power supply for the image intensifier tube and the reinverting prism are all contained within a house just large enough to accommodate these components. The housing has an objective port and an ocular port. Both ports are adapted to be joined to other optical components. As a result, a large variety of optical devices can be attached to either the object port or ocular port of the night vision device, thereby providing night vision capabilities to the optical device.
