Features

Stabilizer™ Hybrid Chamber Design

One of the most important design goal of pneumatic vibration isolator is to achieve lower natural frequency. It is related to the isolator's compliance volume - the larger the volume, the lower the frequency. Unlike the conventional design of a compliance chamber (the volume of which affects natural frequency) and a damping chamber, Newport's patented Stabilizer hybrid chamber design consists of a small size initial chamber and a second damping chamber together as a unified hybrid chamber. 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.

Laminar Flow Technology Boosts Damping Efficiency

Apart from low natural frequency, another indicator of the isolator performance is damping efficiency. It is proportional to the air flow and pressure drop through the damper. Newport's exclusive incorporation of laminar flow damping element in the isolator design largely improves the damping efficiency compared to competitor's single orifice or thin tube design. The laminar flow disks connecting the two chambers create better linkage between piston motion and damping chamber air flow. This 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. S-2000A also uses custom molded ultra-soft diaphragms to reduce the stiffness to further improve the vertical isolation performance.

Trifilar Pendulum Design for Horizontal Isolation

S-2000A's superior horizontal isolation is achieved through a mechanical filter system. Compared with other manufacturers' contacting bearing surfaces, Newport introduces zero friction trifilar pendulum system emerged in energy dissipating oil to eliminate the friction that commonly disturb high accuracy applications, thus enabling isolation to much lower vibration levels as well as high accuracy table repositioning after disturbances. In addition, the S-2000A design features proprietary self centering capability, to better ensure isolator alignment and eliminate horizontal shorting which could happen in other designs.

Modular Support Base

S-2000A isolators are built on modular support bases. Interchangeable spacer bases of different heights allow convenient cost-effective adjustment of working surface height or retrofitting of caster systems. Simply order new support bases LLS-S2000 series to change your isolator to a new height. For example, if you currently have 28 in. legs and would like to change your leg height to 23.5 in., you would order LLS-S2000-423.5 to change 4 legs to 23.5 in. leg height.

High Accuracy Leveling Valves

Automatic leveling capabilities on S-2000A set it apart from other pneumatic solutions, providing precise and fast re-leveling of the entire table system. Newport's IPV series leveling valves offer a wide variety of valve options including the most popular IPV-S1 coming standard with repeatability of ±0.010 in. (0.25 mm), as well as low gain versions for better higher frequency isolation and high gain version for shorter re-leveling time at a slight decrease in high frequency isolation. Newport also offers high-precision version for an improved re-leveling accuracy to better than ±0.002 in.

S-2000A Pneumatic Vibration Isolator Sets

Our isolator sets include the individual isolators and accessories as well as a 3 leveling valve kit, pressure gauge, height adjustment wrench, 1/4 NPT male connector, and S-2000 users manual.

Tie-Bar and Caster System Options

Standard tie-bar/caster systems are available for S-2000A vibration isolators. Be sure to select the S-2000A-XX-TC as well as the TB-XX (without casters) or TBC-XX to complete the tie-bar/caster system. If you are looking at a tie-bar/caster system, you may also be interested in Newport's Integrity VCS or SmartTable OTS table system. Both come standard with a table frame tie-bar frame support to add mobility to the system.

Height Adjustment Capability

Apart from its superior isolation design, the S-2000A also features robust and user friendly mechanical design for better user experience. Newport is the only manufacturer that provides 1.3 inches of height adjustment compensation in the isolator to allow for easy leveling of the entire system or alignment of separate tables. Compared to competitor's solution of using shims or putty before installation, Newport's design brings ease to the system set-up.

SafeLock™ Mechanism Improves System Safety

S-2000A integrates exclusive SafeLock™ mounting clips, offering a safe and reliable connection of the isolator to the optical table. The brackets use a slotted connection to make installation easier. Numerous SafeLock™ secured systems have survived earthquakes throughout California and Japan. Earthquake restraints ERS2010 Series are available as a table accessory. Note: Optical table needs to be customized for Newport ERS earthquake restraints.

Installation Made Easy

Installation is fast and easy with patented, self-centering pistons. They automatically center the piston at the top and bottom of its vertical stroke, guaranteeing unrestricted movement for optimal performance.
