Ultra-high vacuum atomic force microscope
MODEL RELEASED. Ultra-high vacuum atomic force microscope (UHV-AFM). Researcher using a UHV-AFM to study the Casimir force. This microscope is used to study the surfaces of objects at an atomic level. An extremely fine spring-mounted probe,that is either held in contact with the surface or just above it,slowly moves across the surface. Any deflections are recorded and converted into a computer map of the surface. Placing the object to be studied in a ultra-high vacuum greatly increases the sensitivity of the probe. The Casimir force is an attractive force between two surfaces in a vacuum. It causes molecules in nano- machines to stick together,limiting their effectiveness.
