Abstract: A liquid lens can include a cavity between first and second windows, first and second liquids in the cavity, and a variable interface between the liquids, thereby forming a variable lens. The liquid lens can be operable to adjust a shape of the variable interface at an operating temperature less than a melting point of the first liquid. A liquid composition of the first liquid can include at least 65 wt. % water, at most 31 wt. % of a freezing point reducing agent, at most 20 wt. % of an alkali metal salt, a melting point of greater than or equal to −10° C., a viscosity of at most 1.3 cSt, measured at a temperature of 20° C., a refractive index, measured at a wavelength of 589.3 nm, of at most 1.4, and/or an Abbe number of at least 45. A volume of the cavity can be at most 10 μL.

Abstract: A liquid lens device includes: 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 positioned within the cap portion; and a lower window positioned within the base portion, the windows facing and substantially parallel to each other. The lower window comprises opposing primary surfaces and an edge. 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 the edge. The fluids are sealed within the cap portion, base portion, gasket and windows. Further, a height of the edge of the lower window is greater than 0.3 mm and less than 1.2 mm.
