摘要

Abstract

Liquid lens offers a novel approach to achieving large depth of field

wide viewing angle

high speed

and high-quality imaging in zoom optical systems. However

the aperture and reliability limit the lens's performance in various optical applications. The liquid material is crucial for the reliability of the large-aperture liquid lens. To solve the dielectric failure problem associated with the large aperture

we first reveal the mechanism of dielectric failure based on the transport properties of electrolyte solutions and the impact of electrochemical reaction rates from physical chemistry so as to propose a theoretical method to suppress dielectric failure fundamentally. Based on this theory

we develop a series of non-aqueous organic solutions to suppress high-voltage dielectric failure. Next

we identify the optimal formulation for comprehensive optical performance and fabricate a centimeter-level large-apertur

e electrowetting liquid lens. This lens features an optical power variation range of −11.98 m

−1

to 12.93 m

−1

with clear and high-quality imaging function

which can enlarge the field of view and depth adjustment range of holographic reconstructions while maintaining excellent edge clarity of the reconstructed images. The proposed centimeter-level large-aperture non-aqueous electrowetting liquid lens effectively suppresses dielectric failure under high voltage

demonstrates excellent optical performance

and holds exciting potential for applications in 3D display

precision measurement

biomedical observation

and more.
