Liquid lenses configured for thermal exposure resistance and methods of making the same

A liquid lens device, comprising:

• first and second immiscible fluids defining an interface moveable by electrowetting;
• a cap portion;
• a base portion;
• a gasket positioned between the cap portion and the base portion;
• an upper window comprising a glass, glass-ceramic or crystalline material positioned within the cap portion;
• and
• a lower window positioned within the base portion, the windows facing and substantially parallel to each other,
• wherein the lower window comprises opposing primary surfaces and an edge, the edge including a height of greater than 0.50 mm and less than 1.2 mm, wherein the lower window is joined to the base portion with an adhesive, the adhesive positioned in contact with a portion of one or more of the primary surfaces and in contact with the edge,
• wherein the fluids are sealed within the cap portion, base portion, gasket and windows, and
• further wherein the adhesive is a thermoset polymer comprising a hardener and a polymer.
