The dynamic rigidity of a table top (its resistance of the top surface movement from vibration) is the single most important measure of vibration control performance. But compliance curves, the classic method of measuring dynamic rigidity, do not go far enough in providing a quantitative measure of table top vibration control capabilities.
The Dynamic Deflection Coefficient, a figure of merit that can be derived from any compliance curve, enables you to compare dynamic performance directly and select an appropriate level of table stability for your application. When the ambient vibration level is known, the Dynamic Deflection Coefficient can also be used to calculate the Relative Motion value, which can then be used in selecting the most appropriate table for your application.
For easier comparison of Newport table tops, the Dynamic Deflection Coefficient and Relative Motion value for a typical lab environment are specified for all full-size tables and breadboards.
