Patent ID: 8503875

Claim:
A fluidic viewfinder device comprising a support member having an opening forming an aperture; a fluidic lens disposed at least partially in communication with the aperture and support member; wherein the fluidic lens comprises a first optical surface and a second optical surface; wherein one or more of the first optical surface or second optical surface includes an elastic membrane; wherein a fluid is enclosed in at least a portion of the fluidic lens; a band disposed in communication with the support member; wherein the band is disposed in communication with a portion of fluidic lens; a slide member coupled to the support member; wherein the slide member is configured to move parallel to a sliding axis; wherein movement of the slide along the direction parallel to the sliding axis results in a change in tension on the band; wherein the change in tension on the band communicates a change in force on the fluidic lens; wherein the change in force on the fluidic lens results in a displacement of the fluid, a deformation of the membrane, and a change in an optical property of the fluidic lens.
