ABSTRACT:
An optical device having a variable optical surface is given by the combination of an elastic body and a relatively rigid member having an opening and disposed to contact the elastic body to expose a part of the surface of the elastic body. The exposed surface part forms a variable optical surface, the shape of which is changed by deforming the elastic body to vary the focal length.
