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