Hybrid Piezoelectric/Air Active Vibration<br />
Cancellation System<br />
STACIS®iX is a new active vibration isolation<br />
system specially developed by TMC <br />
for <strong>Optical</strong> <strong>Tables</strong>. The system features <br />
excellent vibration isolation properties <br />
both in the low-frequency range, below <br />
10 Hz, and in the high-frequency range, <br />
above 10 Hz.<br />
<strong>Optical</strong> tables are typically equipped <br />
with low-frequency, pneumatic isolation <br />
systems that have a resonance frequency<br />
range around 1.5 Hz. These systems<br />
suppress higher frequencies quite<br />
effectively. In the crucial frequency range<br />
of building vibrations, however, from<br />
1 Hz to 3 Hz, vibrations that come up<br />
through the floor are enhanced. In other<br />
words, in this frequency range the typical<br />
system is actually worse than having a<br />
support system with no vibration<br />
isolation.<br />
For cases such as these, the STACIS®iX <br />
from TMC is the ideal solution. This <br />
patented system comprises a serial <br />
connection of a passive air-isolated <br />
system from the MaxDampAir®series <br />
with an active piezoelectric-electrical <br />
isolation system based on the time-tested <br />
STACIS®technology. The STACIS®system<br />
is equipped with special vibration sensors<br />
that detect low-frequency vibra tion and<br />
neutralize it using piezoelectric <br />
actuators. In addition, the STACIS®iX <br />
system extends the stroke of the piezo <br />
actuator from 15 μm to 60 μm. This <br />
ensures that even large-amplitude vibrations,<br />
as occur particularly in tall buildings,<br />
can effectively be eliminated. The <br />
transfer function of the overall system is <br />
equal to the sum of transfer functions of <br />
the two individual systems.<br />

The series of vibration isolation systems <br />
for optical benches has now been <br />
expanded by the addition of the Laser <br />
Table Baseseries, designed on the <br />
technological basis of the STACIS®iX <br />
technology.<br />
Low-frequency vibrations, beginning <br />
below the 1 Hz level, are damped directly<br />
on the floor by the active piezo electric<br />
isolation system. The passive air-isolated<br />
vibration isolation system from the<br />
MaxDampAir® series is positioned at the<br />
upper end of the support system. The <br />
support system itself is the standard TMC <br />
system with tiebars. Thanks to its <br />
modular design, the overall setup can <br />
easily be modified to suit individual <br />
application requirements. Moreover, <br />
existing passive systems can be retrofitted<br />
with the STACIS®system without <br />
having to remove the optical and mechanical<br />
systems already mounted on the <br />
tabletop. Figure 2 shows the horizontal <br />
and vertical transfer functions of the <br />
individual systems, as well as the total <br />
transfer function of the LaserTable <br />
Basesystem.<br />
