Abstract
A microlens immersed in a nematic liquid crystal cell has been constructed with a variable focal length which can be controlled by applying an analogue voltage to the nematic liquid crystal. The focal length is -910 ± 30 μ m with no electric field applied and with an applied field the focal length can be varied from 380 ± 50 to 560 ± 20 μ m although at present the lens performance is limited by aberrations.
