Abstract

Liquid crystal (LC) varifocal lenses are characterized by their need for compactness and high-speed response, rendering them well-suited for next-generation optical devices. The focal length can be modulated by reorienting LC molecules through acoustic radiation force. In this study, the influence of the geometrical structure of ultrasonic LC lenses on the optical performance was examined. Two LC lenses with distinct glass substrate thicknesses were fabricated, and their optical characteristics were evaluated. The electro-mechanical parameters were found to be altered by the thickness of the glass substrate, which consequently led to an improvement in the power consumption in focus tunability.
