ABSTRACT:
A set of two panes of transparent material brought within proximity to being plane parallel of each others surfaces facing each other; an equidistant space between them is maintained by a perimeter moulding of elastic material enclosing within the two panes a space that is filled with a colloidal liquid of composition, that by compressing the panes together permits light and other electromagnetic wavelengths to pass due to its varying thickness; the compressible elastic perimeter connecting the panes edge together as along its internal edge a trough depression acting as a reservoir for the colloidal liquid to go to when the panes are compressed together by C clamps compressing the panes when their cams are actuated. The panes are held apart by the elastic perimeter moulding.
