The invention describes a tunable liquid crystal lens (1) wherein the upper electrode (4) comprises: a first upper sub-electrode (41) and a second upper sub-electrode (42); an upper transmission line (43) of low resistivity but high resistance electrically connecting the first upper sub-electrode (41) and the second upper sub-electrode (42); and a plurality of upper lead wires (44) electrically connected to different upper transmission line points (43), where the upper lead wires (44) are distributed so as to cover essentially the entire surface of the lens (1) without crossing with each other so that, when voltages (V1, V2) are applied to the respective upper sub-electrodes first (41) and second (42), the difference in voltage between them is distributed over the entire surface of the lens (1).

Applications

Estos diseños presentan aplicaciones en Oftalmología (lentes progresivas) y en dispositivos de realidad aumentada y realidad virtual. Además, estas lentes adaptativas pueden suponer una revolución en la siguiente generación de gafas sintonizables mediante tensión, el zoom óptico y la visión 3D. • Nuevo método de fabricación de lentes adaptativas basadas en cristal líquido. • Sencilla fabricación. Impresión de los electrodos sobre el substrato de vidrio por fotolitografía. • Lentes más sencillas y económicas. Con estos diseños protegidos se requieren menos electrodos (generadores de líneas de tensión). • Estos diseños permiten obtener lentes con fácil control de la tensión, gran apertura, elevada potencia óptica, elevada velocidad de conmutación y se superan limitaciones técnicas previas.
