With noise levels approaching 2-3nm it is capable of resolving step heights as small as 10nm. Variable force and measurement length settings make measurements possible on a wide range of materials and structures. A magnified video targeting system permits positioning the needle tip near small surface features. Stylus tip radius is 12.5 microns.
