We report the development of an optical element that can be dynamically switched between different modes of operation. Namely, it can produce parabolic wavefront and thus focus light, but, when wished, it can be switched into a conical or linear wavefronts producing thus tunable axicons or prisms. The element uses nematic liquid crystals and is based on a simple production technique making it suitable for high volume manufacturing. The basics of its operation as well as of its optical performance data will be reported.
