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.
