OPTICALLY TUNEABLE LENS ASSEMBLIES

In some examples, a method of manufacturing an optically tuneable lens assembly comprises extruding a support structure comprising a monolithic body section defined by a first wall and a second wall separated from the first wall by multiple supporting ribs, the body section comprising a pair of opposing outer side wall sections disposed between the first wall and the second wall at respective outer edges thereof, forming a first opening in the body section, the first opening extending through the body section, forming a second opening in the body section, the second opening extending through the first wall or the second wall and respective portions of a first set of supporting ribs disposed between the first wall and a second wall at a position of the second opening, disposing a flexible optical membrane over, on or within the first opening at the first wall, disposing an optical cover plate over, on or within the first opening at the second wall, disposing a flexible actuator membrane over, on or within the second opening, and sealing the body section at a first edge and a second edge thereof, the first edge and the second edge extending laterally across the body section between the first and second walls and the opposing outer wall sections.
