SmartTable OTS Optical Table System Installation

Learn about how to install your new SmartTable OTS optical table and support system.

SmartTable Active and Broadband Damping Performance

ST Series SmartTable optical table tops feature two IQ active dampers which 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. 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.

The compliance curve shows the positional motion of the structure for a given excitation force and frequency. The dashed red line is the rigid body line showing how an ideal optical table would perform with no relative motion. The blue line shows the natural frequencies of the optical table and how they these deviate from that of a rigid body. The red line shows the full damping performance with active damping turned on.

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.

Easy Set-up with One-Button Auto Tuning

SmartTable active damping products are easy to set up and operate. Simply connect the IQ dampers with controller and press "Auto-Tune" button on the controller, the system will automatically find the resonances of the table and set gain parameters. Once the tuning is finished, the dampers will start working to damp vibrations on your tabletop real time. This feature also enables users to improve their table performance under different payload or payload distributions - press "Auto-Tune" when you have a major change in your set up to achieve the maximized damping performance.

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.

Effective Active Damping

When the IQ damping system is activated, the motion on the table is minimized. Active damping eliminates main resonance vibration peaks in vibration spectra created by random excitation, particularly in the sensitive 100-300 Hz range.

Faster Settling Time

Compared with broadband damping technologies, IQ damping provides much more accurate and timely compensation across the entire working ranges of the actuator-sensor pairs, delivering a quiet tabletop surface for any challenging applications.

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.

High Performance Pneumatic Vibration Isolators

The pneumatic vibration isolators in the supporting frame feature our patented Stabilizer™ hybrid chamber design which consists of a small size initial chamber and a second damping chamber connected by a laminar flow disk. Because the initial chamber is reduced dramatically in size, it forces the isolator to use the second chamber as part of the compliance volume, which greatly increases the compliance volume for a given package size, and greatly lowers the natural frequency. Besides, our exclusive incorporation of the laminar flow damping element creates better linkage between piston motion and damping chamber air flow, which generates a higher damping force for a given piston displacement for faster, more efficient damping. It also lowers the amplification at resonance and improves isolation bandwidth and settling time. The vibration isolation performance is characterized by transmissibility curve which shows the mechanical filtering properties for the isolator leg - how much floor vibration will be transmitted through the leg to the table top.

Super Rigid Trussed Honeycomb Core Design

The honeycomb core in our optical tables 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.

Vertically Bonded Triple Core Interface

All Newport tables are vertically bonded along the height of the honeycomb core. Most other manufacturers forego this extra step because of added expense and time required to apply adhesive to each individual core member. Vertical bonding adds constrained layer damping effects into the core, while maximizing the table’s rigidity-to-weight ratio. The trussed core design enables a triple core interface at each honeycomb cell. Whereas open core designs only have two structural members at each interface, the Newport table has three offering a 50% increase in local rigidity. The three sheets are fully bonded for the full table height producing greater stiffness.

Highly Damped Side Panels

Side panels for optical tables are more than just covers. They should contribute to the overall damping performance of the table. Our optical tables use highly damped composite wood as side panels to help eliminate vibrations from the side. Composite wood has a much better damping performance than steel has a high elasticity and tends to allow vibration or ringing. Materials with low elasticity such as wood tend to dampen vibration and ringing. For example, home stereo speakers are typically enclosed by composite wood to damp the acoustic vibrations.

Individually Sealed Mounting Holes

All of Newport's optical breadboards and tables are with individually sealed mounting holes. Those mounting holes feature 19 mm screw depth and in contrast to some of the other products in the market that has channel for a row of holes or just a polymeric film, Newport's individually sealed holes are more reliable and easier to clean. This is because we believe in the integrity of the product - especially the core. When dust and liquids go into your optical breadboard and table, it may have a long term effect on the damping performance of the product and make the product degrade over time. A good quality breadboard and table lasts long time - tens of years and more. It's a good investment for a product with sealed mounting holes.

Precision Grid of Tapped, Countersunk & Deburred Mounting Holes

The 1/4-20 or M6 tapped mounting holes are countersunk and deburred. This ensures easy thread engagement while eliminating contamination problems. The mounting holes are located on a 1 in. or 25 mm grid with standard grid markings for easy and repeatable component placement.

Unique Pressure Bonding Process Ensures Superior Flatness

Metrology quality steel assembly platens are used to ensure the superior flatness of our optical tables. The platen supports the top surface of the table during the assembly and bonding process and imprints the top surface with the same flatness characteristics. Our platens are the largest and flattest in the industry. We use gravity pressure bonding to apply constant pressure across the optical table during the bonding process ensuring that the top surface conforms to the platen flatness.

SafeLock™ Mechanism Improves System Safety

SmartTable OTS Series integrates exclusive SafeLock™ mounting clips, offering a safe and reliable connection of the frame to the optical tabletop. Numerous SafeLock™ secured systems have survived earthquakes throughout California and Japan. Earthquake restraints ERSW2010 Series are available as a table system accessory. Note: Optical table system needs to be customized for Newport ERS earthquake restraints.
