摘要： Binoculars designed to provide a large aided static field of view are provided. The binoculars are characterized by S/D ratios of above 2.8, where S is the binoculars' aided static field of view calculated by multiplying the binoculars' magnifying power by the binoculars' semi field of view in object space and D is given by tan.sup.-1 [(R.sub.ex +1.5)/13], where R.sub.ex is the radius of the binoculars' exit pupil and where R.sub.ex and the constants 1.5 and 13 are measured in millimeters. As a result of the increased S/D ratio, the binoculars' of the invention minimize the sensation of tunnel vision which normally occurs when binoculars are used and reduce the user's apprehension of missing activities in his or her peripheral vision. In certain embodiments, a movable field lens unit is employed to provide variable power and a negative corrector lens unit is employed for aberration correction and to minimize the size of the binoculars. The binoculars are suitable for mass production and general consumer use.

摘要： A real image zooming viewfinder comprising three optical units with refracting optical power and an additional moving reflective optical unit. Zooming is accomplished by moving one of the refractive optical units and the additional reflective optical unit or by moving the first and the second optical units. The need for field lens is eliminated by having the first and the second unit cooperate to make the finder system telecentric with respect to principal rays at the intermediate image plane.

摘要： A zoom taking lens for a photographic single lens reflex (SLR) camera. The lens has an air space between elements of the lens, which air space is large enough to accommodate reflective means for directing rays which have passed through elements of the lens in front of the reflective means, to viewfinder means. By being able to accommodate the reflective means within the length of the lens and with the reflective means being axially movable the back focal length of the lens may be much smaller than is the case in a conventional SLR camera in which the reflective means is movable into and out of the back focal length between the rearmost element of the lens and the film of the camera.

摘要： 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.
