Effects of orientation in nematic liquid crystal (LC) at non-uniform electric field can be used to create new optical devices. A non-uniform field causes a deformation of nematic director and a radial symmetrical distribution of a refractive index is obtained. This LC-cell possesses the lens properties. The optical properties of LC-microlens with homeotropical alignment of nematic have been researched. The diverging property has been obtained in this structure. The LC-microlens focal length--voltage dependence has been investigated.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
