Abstract (en)

[origin: WO2008024071A1] The present invention provides a variable focus semi-solid zoom lens, methods of making and using the variable focus lens and optical devices containing the variable focus semi-solid lens. The focal length is controllable by changing the shape, size, dimension, geometry, outer diameter or surface curvature of the semi-solid lens. The change of the focal length can be achieved by using a pressure control device coupled with the semi¬ solid lens. The semi-solid lens can also be mounted in a housing.
