A 30 mm diameter electrically tunable liquid crystal lens based on the refractive Fresnel concept is presented. It shows a relatively large optical power variation range and low aberrations. Optical characterizations confirm its potential for good vision recovery.
Electrically tunable liquid crystal lens with 30 mm diameter is presented based on the refractive Fresnel concept. Relatively large optical power variation range (from - 0.74 to +0.71 Diopters) is demonstrated along with very low root mean square aberrations (<=-0.15 mu m). Optical characterizations, including with Snellen chart, show that good vision recovery may be obtained with fast response time (under 500 msec) and relatively low haze. The proposed design is very simple and may be fabricated by using single step lithography. Perspectives on its applications are discussed.(c) 2023 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
