Active, Tuned, and Broadband Damping Performance

SST Series SmartTable HD optical table top delivers the best damping performance among all table tops. Broadband damping is provided by a 4.8 mm thick table skin, a constrained layer core that attenuates broadband vibration, a damped working surface that eliminates skin resonance, and a composite edge finish that eliminates sidewall resonance. Two precision tuned dampers selectively eliminate two fundamental structural table modes and their entire harmonics. Two IQ active dampers effectively address medium frequency resonances of optical tables by sensing the vibrations and driving shakers at the opposite phase of the vibrations to cancel them out.

Tuned Mass Damping - The Most Effective Passive Damping Method

Hybrid Damped and Upgradable SmartTable® optical table systems feature precision 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 broadband, our tuned mass damping method targets at resonances and as a result is much more effective. The 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. Once tuned at factory the dampers are locked securely and the frequency would not shift during shipping of the table.

Intelligent Q (IQ) Active Damping Technology

At the core of our SmartTable optical table tops is an advanced damping technology called Intelligent Q (IQ) Damping. It effectively addresses the medium frequency resonances of optical tables from 80 to 550 Hz by incorporating two pairs of sensors and actuators in the optical table top design. An external controller is used to coordinate the signal processing, enabling a fast and accurate damping response. Each sensor-actuator pair is controlled by a separate control channel. The sensor senses the vibrations and the actuator outputs a signal to compensate for the vibrations. The pre-amplifiers and band-pass filters condition the sensor output signal before feeding it to the digital controller. The digital controller implements recursive filters that compensate for the dynamic response of the shaker and correct the phase to bring the phase difference between the displacement and force close to (-π/2) in the desired frequency range.

24/7 Vibration Monitoring Capability

The ST-300 active damping controller comes with powerful and intuitive software that allows user to generate FFT plots, time response plots and save graphs or export data for further analysis. The ST-300 software also provides time continuous 10 to 820 Hz vibration data monitoring that could be used as a system trouble shooting tool for long duration experiments.

Robust and Flexible Pneumatic Isolated Frame Support

The SmartTable OTS optical table system features a sturdy and multi-functional support frame that is designed to maximize utility, minimize space occupied and optimize structural rigidity. The support legs feature pneumatic isolators to passively absorb vibrations from the optical table's environment. The frame features leveling feet and casters for easy transportation of the system. A wide variety of accessories are compatible with the SmartTable OTS frame and can be used to customize your optical table system.
