Newport Corp. has added the S-2000-TC to its S-2000 Stabilizer series pneumatic vibration isolators, which are compatible with tie bars and casters. The instrument has a 2000-lb load capacity, supports large-area subfloors and is suitable for isolating optical tables, large inspection equipment and heavy machinery. The individual legs can be bolted together to improve mobility and system rigidity. Heights range from 16 to 28 in., and all models are equipped with precision pneumatic re-leveling valves and float-height indicators. SafeLock mounting clips secure the isolators to the bottom of the company’s optical tables. Vertical resonant frequency is 1 Hz, and vertical isolation efficiency is 90% at 10 Hz. Horizontal isolation starts at 2.5 Hz and reaches 95% efficiency at 10 Hz.
