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 pneuamtic isolators and outstanding damping technology.
Dual Chamber Design
DAEIL's pneumatic vibration isolators consist of the two chambers that are uniquely designed and developed to lower its natural frequency and increase damping efficiency.
Exceptional Vibration Isolation Performance
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.
The second chamber is a damping chamber which is linked with the air chamber through a orifice. As the air chamber creates the restoring force, the air flows into the damping chamber, and the orifice dissipate the energy in the air, damping the system and improves stability. 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 very strong for large displacements of the piston and less for small displacements. This allows for fast setting of the payload, without compromising 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 - Leveling Valves
The high-performance leveling valves automatically relevel a 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 must be selected.
