Description
The Duo elements have been engineered for medium weight instruments (600kg to 1600kg) with a complex geometry, e.g. UHV-STM, or setups with distributed structural elements. The basic Duo configuration consists of two Duo elements connected by a rigid plate or frame, e.g. a breadboard. The basic configuration can be extended by by additional elements if a bigger load capacity or higher compensation forces are required. Combinations of 3, 4 or more elements are possible.
*Floating table top is supported by steel springs; low-pass characteristics of spring-mass combination dominates the dynamic behaviour above 200 Hz.
The maximum compensation level depends on several conditions, such as payload, frequency, load distribution and height of the payload as well as the distance between the isolation elements.
