Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
129 words
In an optical system for recording panoramic images with a photographic camera having a lens mounted within a lens barrel the combination comprising a reflector containing a surface of revolution, the axis of said surface of revolution being concentric with the viewing axis of said camera, and said surface of revolution being so oriented with respect to said camera lens as to reflect a view of the panorama along said camera axis, means for mounting said reflector in spaced position in front of the lens of said camera, said means for mounting comprising at least one transparent stem member having one end adapted for connection to the lens barrel of the camera and the other end adapted to support said reflector, whereby said camera can record a panoramic image
