Objective lens system, relay lens system, and eyepiece lens system for night-vision goggles

摘要: The goggles include a pair of optical assemblies, each having two intersecting paths, including see-through path with large field view on straight line sight to the viewed object, and folded which includes an objective lens set, intensifier converts visible infrared light intensified light, eyepiece arranged in loop plane perpendicular path. Infrared from object enters both paths. A dichroic prism combiner at intersection paths reflects into transmits all other light. In one embodiment separator is disposed forward for transmitting portion incoming along reflecting remainder another embodiment, entrance spaced
