Abstract

A fluidic stabilized focus device comprises a fluidic lens core and a first yoke. The fluidic lens core includes a support ring, a first surface that includes an elastic membrane, a second surface, and a volume of fluid enclosed within the boundaries of the first and second surfaces and support ring. The first yoke has an annular portion configured to engage the first surface. Engagement of the first surface by the first yoke results in a displacement of the fluid and a change in optical properties of the device.
