Design of a tabletop dynamic force microscopy setup

We develop a low-cost tabletop dynamic force microscopy (DFM) setup using an autocollimator with sub-microradian sensitivity to measure the deflection of a gold-plated cantelever. We demonstrate the functionality of the device through measurement of the electric force at micrometer scales, with intent to extend the apparatus for measurements of casimir forces and tests of the gravitational inverse square law.
