Vibration Isolation | Dan Berard

Vibration Isolation. The STM head is mounted on a stack of three 5″ diameter x 1/2″ thick steel plates each separated by 3 small pieces of viton perfluoroelastomer cut from an O-ring. Viton is a pretty effective vibration damper. This stack is mounted on an MDF plate and aluminum plate, which is suspended by three 2′ long springs.

Scanning tunneling microscope - Wikipedia

A scanning tunneling microscope (STM) is an instrument for imaging surfaces at the atomic level. Its development in 1981 earned its inventors, Gerd Binnig and Heinrich Rohrer (at IBM Zürich), the Nobel Prize in Physics in 1986. For a STM, good resolution is considered to be 0.1 nm lateral resolution and 0.01 nm (10 pm) depth resolution.
