Abstract

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 µm). Optical characterizations, including with 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.

摘要

基于折射菲涅尔概念，展示了直径为30毫米的电可调液晶透镜。其展示出了相对较大的光焦度变化范围（从-0.74到+0.71屈光度）以及非常低的均方根像差（≤0.15微米）。包括视力表在内的光学特性表明，该透镜具有快速响应时间（低于500毫秒）和相对较低的雾度，可能实现良好的视力恢复。所提出的设计非常简单，可通过单步光刻制造。文中还讨论了其应用前景。
