In this paper, we present a hybrid interferometer which allows the measurement of the aberrations of micro-lenses as well as the specification of the focal length, thickness, and radius of curvature. The Twyman-Green and Mach-Zehnder interferometers are experimentally combined for full characterization of micro-lenses. This hybrid interferometer is equipped with a Shack-Hartmann wavefront sensor for testing the quality of micro-lenses in transmission. We describe the technique and report some experimental results.
Keywords: Aberration, Interferometry, Lens parameters, Shack-Hartmann sensor
