Abstract: An atomic force microscope which is readily useable for researchers for its intended use without extensive lost time for setup and repair. The probe used therein is a cantilevered optical lever which imparts surface information in a gentle and reliable manner by reflecting an incident laser beam. The probe is carried by a replaceable probe-carrying module which is factory set up and merely inserted and fine tuned by the user. The probe-carrying module also includes the provision for forming a fluid cell around the probe. Fluid can be inserted into and/or be circulated through the fluid cell through incorporated tubes in the porbe-carrying module. Electrodes are also provided in the fluid cell for various uses including real-time studies of electro-chemical operations taking place in the fluid cell. The piezoelectric scan tube employed includes a voltage shield to prevent scanning voltages to the tube from affecting data readings. Samples are easily mounted, replaced, and horizontally adjusted using a sample stage which is magnetically attached to the top of the scan tube. Calibration tools are provided to make initial set up and fine tuning of the microscope a simple and straightforward operation requiring little or no technical talent.

- 29 Jun 2004
TL;DR: In this article, a method for forming a topographical image of the heterogeneous variations in a surface of a material has a first machining step and a second scanning step, which produces a machined surface whose local elevations relative to a datum plane are dependent on the local hardness or wear resistance of the surface.
