I-500 Series Pneumatic Isolators

Product catalog summary

Technical Reference Overview
This document provides a comprehensive overview of optical tables and vibration control systems, focusing on honeycomb, granite, and rigid structures, as well as breadboards, grid platforms, isolators, workstations, and isolated platforms. It also covers structural rails and carriers, along with testing, analysis, and design considerations.

I-500 Series Pneumatic Isolators
The I-500 Series IsoDamp Isolation System is designed for systems requiring high horizontal acceleration loads and fast settling times. It features increased damping without compromising isolation at higher frequencies. Key features include:

Self-centering and non-rotating design for easy integration.
Horizontal pendulum design with horizontal damping for quick settling times.
Hybrid chamber design for optimized isolation across the load range.
High accuracy leveling valves for improved repositioning after disturbances.

Performance Specifications
The document provides detailed specifications for the I-500 Series, including:

Vertical and horizontal isolation resonance frequencies and percentages at 5Hz and 10Hz.
Amplification at resonance for both vertical and horizontal directions.
Damping elements and airflow specifications.
Load capacity per isolator.

Graphical Data
Graphs illustrate transmissibility across vertical and horizontal frequencies, and stage acceleration data is provided for a 20 kg moving mass with specific motion parameters.

Ordering Information
Details on model payload requirements are provided, specifically for the I-500-410 model, which is suitable for motion systems with high horizontal acceleration.

Newport’s patent pending I-500 IsoDamp Isolation System damps high amplitude vertical displacements without adversely affecting isolation at higher frequencies or causing extended settling times as seen with heavy oil damping systems. The I-500’s horizontal pendulum isolation system provides superior isolation at low vibration levels compared to friction prone gimbaled and bearing systems. This unique horizontal damping system dissipates stage motion energy with very little compromise of isolation while minimizing settling time. • Self-centering and non-rotating design eases isolator/platform integration • Horizontal pendulum design combined with horizontal damping provides quick settling times • Hybrid chamber design optimizes isolation throughout the load range • High accuracy leveling valves improve repositioning after a disturbance Vertical 0.5 1.0 10.0 45.0 TRANSMISSIBILITY (T) -40.0 -30.0 -20.0 -10.0 0 10.0 20.0 -50.0 VERTICAL FREQUENCY (Hz) Horizontal 0.5 1.0 10.0 45.0 TRANSMISSIBILITY (T) -40.0 -30.0 -20.0 -10.0 0 10.0 20.0 -50.0 HORIZONTAL FREQUENCY (Hz) 0 .5 1.0 1.5 100.0 0 -100.0 MILLI - G STAGE ACCELERATION BASIS (TABLE MOTION) DATA TAKEN WITH A 20 KG MOVING MASS, 3 MM STEP SIZE, 0.5 G ACCELERATION, 100 MM/S VELOCITY.
