Hybrid damping system is the most advanced damping technique for optical tables and provides the best performance optical tables ever in the market. The active system is able to further reduce vibrations on top of a good foundation created by precision tuned dampers, delivering optical tables and systems with the minimum resonance peaks. Hybrid damping combines the advantages of both active damping and tuned mass damping. For more information about active damping, see our technical note Active Vibration Damping. It has a much shorter settling time than passive system and reduces all table resonances within the entire active bandwidth. It effectively addresses the resonances of optical tables by incorporating two pairs of sensor and actuator in the optical table design and uses an external controller to coordinate the signal processing, enabling the fast and accurate damping response for optical tables. Different from broadband or tuned mass damping that absorbs vibrations passively, Newport’s SmartTable ® line of products feature active damping with patented IQ technology (US patent 7320455, 8196891, 8807515, 9086112, 8276873, 8231098, 86514585) that senses vibration in real time and immediately sends out signals to actuators to counteract and cancel the vibrations. ![]() Newport introduced the first commercially available actively damped optical tables in 2005. It is usually affordable and good for applications that do not require high damping performances. Newport's RPR Reliance™ Series broadband damped optical tables represented the state-of-the-art optical table tops before the advent of tuned damping, and they still offer good value for many less stringent applications. Broadband damping does not target any specific table resonance or any specific set of frequencies instead it absorbs and dissipates vibration energies uniformly across the frequency range. It may also involve mass blocks/plates and rubbers installed along the side of the table to absorb moderate amount of vibrations for a broad frequency range that covers the resonances of a standard size optical table. Typically the broadband damping involves energy absorption materials such as foam, rubber or elastomers. It is widely used in anti-vibration tables to reduce the structural vibrations of the tabletop. Broadband damping absorbs and dissipates vibration energies across a broad range of frequencies.
