Abstract:

An eyecup assembly for a submarine periscope blinder assembly includes an annularly-shaped ring having a multiplicity of holes, which are unthreaded, extending therethrough and adapted to receive screws for securing the eyecup assembly to a like multiplicity of holes which are threaded and arranged in a circular pattern around an eyepiece opening in the blinder assembly, the ring defining a central viewing opening. An eyecup lateral shell circumscribes the eyecup chamber and is fixed to the ring and configured to conform generally to an eye area of a viewers head, and to be interchangeably mounted to the threaded holes to receive either the viewers left or right eyes by selectively indexing the holes in the ring 1800 apart relative to the threaded blinder assembly holes.
