Paper Abstract

The vibrational and interferometric performance of optical tables employing automobile inner tubes as vibration isolating elements is investigated. A relation allowing the resonant frequency of a table to be determined during design is presented and verified. Michaelson interferometer fringe drift data is displayed which compares the interferometric performance of two arbitrarily selected inner tube tables to a typical commercial optical table. The use of a bare concrete floor as a suitable optical platform is explored resulting in fringe drift times of 2.6 hours. Table top construction and air current suppression are recognized as more important factors than vibration isolation in establishing interferometric stability at ground floor levels.
