Periscopic sight with a unitary lens system
Реферат: Abstract of the Disclosure A periscopic sight is mounted to extend through the wall of protective armor surrounding a gun station. An elevation mirror is exposed to receive light from the direction in which the gun is pointing and to reflect the light along a vertical path extending through the sight. A sealed unitary lens system has a lens axis aligned with the vertical path and conducts the light therethrough to a stationary mirror accessible to the eye of an observer. The sealed unitary lens system has a sufficiently long eye relief to provide an unobstructed image to the observer in spite of the placement of the stationary mirror between the lens system and the observer. -1a-
