Pneumatic Optical Table
The pneumatic optical table has a high-precision honeycomb tabletop, with diaphragm air spring isolation units and leveling valves underneath, using compressed air for passive vibration damping. Its low natural frequency effectively isolates ground vibration, while the tabletop's dense array of standard threaded mounting holes facilitates the assembly of optical components. It is commonly used in optical experiments such as laser experiments, precision inspection and microscopic observation. The complete pneumatic optical table consists of a honeycomb-core aluminum alloy tabletop, a steel support frame, diaphragm air spring isolation components, level control valves and an air supply treatment unit. The precision-machined tabletop has an array of threaded mounting holes for flexible mounting of optical mounts, lasers, detection sensors and other components. Diaphragm air springs underneath act as passive isolation elements, providing elastic support through a sealed air layer. A Levelling Valve automatically maintains tabletop level. The product has a low natural frequency and efficiently attenuates high-frequency ground vibration, preventing vibration disturbances from affecting optical path accuracy. It produces no electromagnetic interference during operation and offers high stability. The table is widely used in university research laboratories and corporate research and development centers for optical research and industrial measurement applications with demanding vibration requirements, including laser interferometry, spectral analysis, microscopic inspection and precision photolithography inspection.
