Atomic Force Microscopes which are quite susceptible to external vibrations, are able to measure topographic images at resolutions below 0.1 nanometers. The external vibrations need to be reduced in order to obtain the highest-quality AFM images, particularly for high-resolution scanning.
Both acoustic and and structural vibrations degrade the resolution and overall performance of Atomic Force Microscopy Instrumentation. The acoustic vibrations can be reduced by placing the microscope in an acoustic isolation chamber. On the other hand, structural vibrations can be reduced by using a mechanical isolation platform such as an active vibration table.
The vibration isolation tables are designed to provide stable working conditions for devices that are sensitive to vibration and shocks. The table consists of an outer table frame that supports the main work surface which is not isolated from vibration and an inner table frame that is entirely separate and supports the inner isolated work surface. This ensures vibrations are not transmitted to the isolated inner work surface. An Active Vibration Table uses a feedback control method for removing vibrations. An acceleration sensor measures vibrations and then electromechanical transducers use the output of the sensors to control the motion of the tabletop.
The advantage of an Active Vibration Table over the Bungee option is that the Vibration Isolation Tabletop is more stable than a platform suspended with bungee cords. Other equipment that provide vibration isolation include vibration enclosures, bungee options, and custom/OEM enclosures.
This being said, bungee solutions are often better for structural vibration reduction than active vibration tables.
