  • Calculation of operating voltages for specific optical powers (+1.00 D to +3.00 D).

    • Main Results:

    • The computational model is up to 40 times faster than previous techniques.
    • Optimal insulation thickness to lens diameter ratios were identified (1:2 to 1:3).
    • An approximately linear relationship between applied voltage and optical power was demonstrated for powers under +3.00 D.

    Conclusions:

    • The developed multigrid model enables rapid assessment and optimization of liquid crystal lenses.
    • The study proposes a novel, lower-voltage operation method for these lenses.
    • The model's versatility is shown through the simulation of in-plane electrode liquid crystal devices.
