  • Patent number: 4072406
    Abstract: A camera periscope presenting low visual obstruction to the viewer is disclosed herein having a housing carried on a camera body enclosing image conveying components between a front open window and a camera lens. The housing includes an open window through which the viewing image is conveyed to a beam splitter device so that the image branches along a first optical axis to the eye of the viewer and along the second optical axis to the camera lens. The front and rear panels of the periscope housing utilize light control films or panels so that the viewer has sufficient vertical tolerance of his eye position and yet stray light is prevented from reaching the camera lens. The sides of the housing are of opaque material including thin or narrow transverse bridges employed to support the light control films or panels so that the viewers visual image is not substantially obstructed thereby.
