Abstract

We have developed a variable-power zoom system that incorporates fluidic lenses and has no moving parts. The designed system applies two single-chamber plano–convex fluid singlets, each with their own distinct design, as well as a conventional refractive lens. In this paper, we combine the two fluid elements to form a variable-power telescope, while the fixed lens enables image formation. In this configuration, the image plane location is fixed. By synchronizing the powers of the two fluidic lenses, we produce a varying magnification zoom system. The design of each lens and the coupled system is analyzed. The coupled device experimentally produced a magnification range of $0.1\times$ to $10\times$ zoom or a $20\times$ zoom magnification range with no moving parts. Furthermore, we expand on optical performance and capabilities of our system with fluidic lenses relative to traditional zoom lenses.
