Abstract

In this study, the opto-mechanical design and functional characterization of a Variable Focal Liquid Length Lens (VFLLL) are presented. This VFLLL is formed by a hydro-pneumatic system, a mount with two elastic membranes and the liquid medium between them. The hydropneumatic system allows the entrance and exit of the liquid at any moment to change the shape of the surfaces as well as the axial thickness of the lens. The functional characterization consists in measure the spherical aberrations present in VFLLL when changes on the amount of liquid medium are made. We used the Zygo interferometer to measure the spherical aberration. The changes of aberration as function of the focal length are shown. Finally the experimental results are presented.
