Abstract
A variable focus lens comprises a chamber containing a conductive liquid () and an insulating liquid () of different refractive indices, the surface of contact between the two liquids forming a deformable refractive surface () whose periphery is caused to move along the walls of a housing under the effect of an electric voltage (V). The housing comprises an upper portion () inclined relative to a plane perpendicular to the optical axis (Δ) of the lens, a lower portion () more inclined than the upper portion and a zone of junction (B') between the upper and lower portions, playing the role of a stop for the deformable refractive interface.
