Abstract
A fluidic viewfinder device may include a support member having an opening forming an aperture and a fluidic lens disposed at least partially in communication with the aperture and support member. The fluidic lens may comprise a first optical surface and a second optical surface, one or more of which includes an elastic membrane. A fluid may be enclosed in at least a portion of the fluidic lens. The optical properties of the fluidic lens may be changed by displacement of the fluid, e.g., due to movement of a slide member or a rotating yoke.
