Pneumatic Isolator Support (Tie-Bar Type) / OSDVIO-S-L-TB series

The primary goal of designing vibration isolators is to lower the natural frequency of isolators as low as possible, in order to filter ambient vibrations in buildings, before the vibrations can reach and disturb the optical tops. Our integrated pneumatic supports achieve in isolating the low frequency vibrations through the dual-chamber pneumatic isolators and outstanding damping technology.

Details

Superior Damping
The second chamber is a damping chamber which is linked to the air chamber through a orifice. As the air chamber creates the restoring force, the air flows into the damping chamber, and the orifice dissipates the energy in the air, damping the system. As the piston moves up and down, air is forced to move through the orifice, producing a damping force on the payload. This type of damping is strong for large displacements of the piston and less for small displacements. This allows for fast settling time of the payload, without compromising on small amplitude vibration isolation performance. The orifice installed between the air chamber and the damping chamber quickly restricts the movement of the optical table top or the external force applied to the optical table top.

Automatic Leveling
The high-performance leveling valves automatically relevel an optical table top, offering a wide range of leveling valves options, starting from the standard leveling valves with leveling repeatability of ±1.0 mm to the precision leveling valves with leveling repeatability of ±0.05 mm. If the settling time, leveling accuracy and leveling repeatability are required to meet equipment specifications, then the precision leveling valves should be selected.

Dual Chamber Design
The pneumatic vibration consists of two chambers that are uniquely designed to lower its resonant frequency for the better vibration isolation performance in the low-frequency range and increase damping efficiency. The size of an air chamber is optimized and sealed with a ultra-soft rolling diaphragm and a piston, softening the stiffness to further improve the vertical vibration isolation performance. A gimbal support of the pneumatic isolator as a mechanical filter system acts as a gimbal to minimize friction and reduce horizontal displacements.
