AB New analytical expressions for designing liquid crystal microlenses have  been proposed. Equations involved, based on a novel equivalent electric  circuit, lead to optimum designs of liquid crystal lenses which lens  diameter ranges from few micrometers to one millimeter. A particular  mathematical relationship between the microlens thickness and diameter  is the key parameter to achieving a quasi-parabolic phase distribution  across the microlens diameter. Frank-Oseen equations have been used for  modeling and solving the problem. A solution for the elastic constants  of a hypothetic liquid crystal, proper for a microlens device, is  proposed. Manufacturing parameters of the lenses have been designed for  fulfilling focal length and diameter requirements. Some of them are the  thickness, the electrode configuration, and the driving scheme (modal or  hole patterned). A set of liquid crystal microlenses has been  manufactured and an electrooptic characterization has been carried out  in order to compare the measurements with the analytical approach.
