Optical Table, 6 Tuned Dampers, 4 x 8 ft., 8 in. Thick, 1/4-20

The RS4000-48-8 Research Grade Optical Table features unmatched vibration immunity. The RS4000 Series combines Newport’s uniquely rigid trussed honeycomb core with our highest level of tuned damping. This 8 inch thick optical table has a 4 foot width, a 8 foot length, and 1/4-20 holes on a 1 inch grid. Its supreme stability has meant the difference between success and failure in countless leading edge applications. Originally designed for high end interferometric research, the RS4000 is the best choice for extremely sensitive measurements requiring the utmost in vibration control.

Tuned Mass Damping

RS4000 optical tables use Tuned Mass Damping (TMD) technology to eliminate table resonances. TMD is the most effective method among all known passive damping methods, as it concentrates damping efforts where it's needed at the frequencies of dominant resonance modes. It is widely used in various industries for its efficiency and effectiveness of damping, such as the famous Grand Canyon Skywalk, Taipei 101 Building, and NASA's Ares I rocket. Compared to our top competitor's broadband damping methods which absorbs a moderate amount of vibration energy equally over the broad band, Newport's tuned mass damping method targets at resonances and as a result is much more effective. Our precisely tuned dampers work from as low as 25 Hz and go all the way up to 525 Hz, creating opportunity for optimum damping on larger optical tables, the resonances of which often fall outside of competitor's broadband frequency range.

RS4000 Broadband and Tuned Damping Performance

RS4000 Series optical tables are a culmination of many years of experience, innovation and attention to detail leading to unmatched vibration immunity. RS4000 tables feature a 4.8 mm thick optical table skin, a constrained layer core, damped working surface and composite edge finish to provide broadband damping. Six precision tuned dampers are included to selectively eliminate four fundamental structural table modes and their entire harmonics. Originally designed for high end interferometric research, these optical tables are the best choice for extremely sensitive measurements such as live cell imaging, high resolution imaging, interferometry, experiments with long exposure time and so on.

Super Rigid Trussed Honeycomb Core Design

Newport's honeycomb core is different than our competitors. Each piece of the corrugated honeycomb steel sheet is emerged in proprietary elastomeric vibration absorbing materials and bonded vertically throughout the height of the optical breadboard or optical table, creating a much stiffer honeycomb core structure. This labor intensive procedure makes sure that Newport's optical breadboard or optical table has the most robust honeycomb structures.
