Patent ID: 8693104

Claim:
An optical lens comprising: a front curve lens comprising a front curve lens exterior surface and a front curve lens interior surface, wherein both said front curve lens exterior surface and said front curve lens interior surface comprise an arcuate shape; a back curve lens comprising a back curve lens interior surface and a back curve lens exterior surface, wherein both said back curve lens interior surface and the back curve lens exterior surface comprise an arcuate shape, said back curve lens positioned proximate to said front curve lens such that said front curve lens interior surface and said back curve lens interior surface form a cavity therebetween; a volume of saline solution and oil contained within the cavity formed between said front curve lens interior surface and said back curve lens interior surface, said volume of saline solution and oil comprising a meniscus therebetween; and a meniscus wall comprising a first segment including a shape generally of a conical frustum in mechanical communication with a second segment including a torus, wherein the torus is generally convex to an optical axis formed through the front curve lens and back curve lens and bordering the meniscus; and additionally comprising a channel through one or both of the front curve lens and the back curve lens and a conductive material filling the channel.
