Optical Table, 2 Tuned Dampers, 4 x 8 ft., 18 in. Thick, 1/4-20

The RS2000-48-18 Research Grade Optical Table provides 50% of the damping found on the RS4000. This 18 inch thick optical table has a 4 foot width, a 8 foot length, and 1/4-20 holes on a 1 inch grid. The RS2000 series matches the top of the line performance from competitive models. The unmatched low frequency superiority of Newport vibration absorber tuned damping technology allows its larger sized tables to out perform all competitive models. Its supreme stability has meant the difference between success and failure in countless leading edge applications.

Tuned Mass Damping

RS2000 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.

RS2000 Broadband and Tuned Damping Performance

RS2000 Series optical tables are a culmination of many years of experience, innovation and attention to detail leading to unmatched vibration immunity. RS2000 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. Two precision tuned dampers are included to selectively eliminate two 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 requiring the utmost in vibration control.

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.
