Abstract

We present a straight forward and practical method for joining pneumatically floated optical tables with no previous preparation. In order to demonstrate this method we joined two optical tables in an uncentered "T-shape" using twenty four stainless steel plates (SSP), and used a Michelson interferometer to compare the stability of the entire "T"-structure versus one of its parts alone, finding that they both show similar rigidity. We also evaluated the performance of two different master-salve leg configurations by calculating the stress on the joint and confirmed the calculations by Michelson interferometry. In terms of floor vibration damping, it was observed that the performance of the system for the joined "T"-table seemed to be comparable to that of a single segment. This method can significantly reduce costs of large optical tables and will be useful to extend existing optical tables without manufacturer modification.
