ABSTRACT:
A wide angle trapezoidal periscope is disclosed having an upper trapezoidal housing and a smaller lower trapezoidal housing secured to said upper housing having optics sealed therein which include parallel upper and lower windows and parallel upper and lower mirrors. When used on military vehicles, the lower trapezoidal periscope housings are inserted within evenly and closely spaced trapezoidal openings in the rim of a hatch and are secured to the hatch with corner connectors to clamp non-parallel walls of said upper housings within about 1/8 of an inch of the adjacent non-parallel walls of the next adjacent trapezoidal housing. Each periscope provides a vertical field of view of about 43.degree. and a horizontal field of view of about 140.degree..
