Newport Light Load OEM Isolators provide unsurpassed pneumatic vibration isolation for platform loads up to 1300 lbs. Featuring Newports unique Stabilizer hybrid chamber design, these isolators offer the largest compliance volume and, therefore, best vertical isolation of any isolators in this size range. For machinery with moving loads, these damping isolators provide high damping and fast settling with very little compromise of isolation properties. Newports wide selection and modular design capabilities provides the greatest flexibility to precision machinery designers.
Since isolation is best achieved at full rated load, three distinct light load diaphragm designs are offered. When integrated into 3 or 4 leg systems, the Light Load OEM Series enables the engineer to optimize the system by selecting from a range of six full load capacities. Also available are a variety of valves and damping mechanisms to further tune the system to specific machine needs. Eighteen standard configurations are listed while countless more are available though Newports Custom Products Engineering Group.
High-Resolution Systems A Series Stabilizer Isolators
In many high-resolution systems, such as interferometers, profilers and AFMs, very low-level vibration noise is the ultimate measurement limitation. Newports A Series Light Load Isolators offer the same advanced hybrid chamber technology developed for the research grade I-2000 isolators - which means isolation that is unsurpassed for this size range of pneumatic isolator. The A Series is the best choice for most high-resolution applications.
High Throughput Systems B Series Damping Isolators
Building on Newports unique Stabilizer technology, B Series Damping Isolators offer increased damping and reduced platform-settling time and incorporate high gain valves and constrict the airflow through the damping element by 50%. The B Series is an excellent selection for high-resolution systems with an increased requirement for releveling speed and stability as loads are moved across the platform. Custom Damping designs can be turned for specific isolation and moving load requirements.
High Throughput Systems C Series HD High Damping with Horizontal Damping
Systems with high acceleration horizontal loads require increased isolator damping. Based on Newports long experience manufacturing fast motion air bearing and linear stages, version C Series HD High Damping with Horizontal Damping adds high horizontal damping to our standard Stabilizer and High Damping design elements. Newport's horizontal pendulum isolation systems provide superior isolation at low vibration levels over friction prone gimbaled and bearing systems. This unique horizontal damping system dissipates stage motion energy with very little compromise of isolation.
Non-Magnetic Designs
The Light Load Series has a polycarbonate housing and can be modified for applications requiring non-magnetic isolators. Applications include: Nuclear Magnetic Resonance (NMR), superconductor research and other high magnetic field applications. Please contact the Custom Products Group for this capability.
