Paper Abstract

Recent times have seen the production of normal and micro liquid lenses with variable focal length. These have been specially made with transparent elastic materials and liquid medium between them, or with a dielectric liquid medium inside the cavity. Change in the volume of the liquid medium, in the first case, or the application of an electric field as in the second, produced a change in the optical parameters of the lens. The present study offers the opto-mechanical design, manufacture and characterization of a solid elastic lens made of Polydimethylsiloxane (PDMS). To do so, we have prepared a mechanical support frame to hold all of the components of the lens and also allow for the application of radial stress on its periphery. In order to ensure a well-finished lens surface a high quality optical glass mold has also been constructed. Finally, we will present an analysis of the properties of this type of lens when it undergoes variations of radial stress. The experimental results are presented.
