Design and fabrication of a focus-tunable liquid cylindrical lens based on electrowetting.

open access: yesOptics Express, 2022
In this study, a focus-tunable liquid cylindrical lens based on electrowetting was designed and fabricated. The cylindrical cavity usually used in common electrowetting zoom spherical lenses was replaced by a 20 mm × 10 mm × 8 mm cuboid cavity, in which ...

Electrowetting and Surface Tension of Chromonic Liquid Crystals

open access: yesCrystals, 2023
In this work, we report on measurements of the contact angle of sessile droplets of aqueous solutions of a chromonic liquid crystal at different temperatures and concentrations and on different hydrophobic surfaces, and we show that the wettability of ...
