Introduction
Andreas Christian Stemmer is a notable inventor based in Muttenz, Switzerland. He has made significant contributions to the field of microscopy and optical technologies. With a total of 2 patents, Stemmer's work showcases his innovative approach to solving complex scientific challenges.
Latest Patents
Stemmer's latest patents include a scanning probe microscope and a method for operating the same. This scanning probe microscope features a primary control loop that maintains the phase and/or amplitude of deflection at constant values. Additionally, it incorporates a secondary control loop that keeps the frequency of the cantilever oscillation constant by applying a suitable DC voltage to the probe while simultaneously applying a conservative AC excitation. This active control system allows for rapid determination of the contact potential difference or related properties of the sample.
Another significant patent is focused on tunable optical active elements. This invention encompasses various optical active elements, such as tunable diffraction gratings and tunable phase shifters. These elements include an intermediate layer made from a deformable material, mechanically interconnected to a driving means. The driving means consists of two driving plates arranged opposite each other, which compress the intermediate layer, resulting in a change in the optical behavior of the element.
