Embodiment Construction

[0018] The present invention provides a liquid meniscus lens having at least one of a front curve lens and a back curve lens defining a meniscus cavity of the liquid meniscus lens.

[0019] the term

[0020] In this specification and claims related to the present invention, the definitions of various terms used are as follows:

[0021] Contact Angle: The angle at which the oil / salt solution interface (also known as the liquid meniscus boundary) contacts the meniscus wall. For a linear meniscus wall, the contact angle is the angle measured between the meniscus wall and a line tangent to the liquid meniscus boundary at the point where the liquid meniscus boundary contacts the meniscus wall. For a curved meniscus wall, the contact angle is the angle measured between a line tangent to the meniscus wall and the liquid meniscus boundary at the point where the two meet.

[0022] Lens: As used herein, a lens refers to an article having a front surface and a back surface that is op...
