Abstract

Based on selected liquid and elastic polymers, Optotune has developed adaptive optical components, such as focus tunable lenses and laser speckle reducers. The lenses range from 2 to 55mm in aperture, are mechanically or electrically actuated and offer a continuous range of focal powers of several 10 diopters. This additional degree of freedom enables the design of compact optical systems, typically with less mechanics. We show how tunable lenses can be used to improve optical designs for imaging and illumination systems in terms of size, quality and speed. The speckle reducers are based on electroactive polymers and offer an extremely compact and low cost solution for removing speckles, which is a key benefit for laser projectors and illumination systems.
