In scenarios requiring ultra-high sensitivity and precision such as interferometry measurement, nano-microscopy, ultra-precise lithography, quantum optics, and laser micro-processing, ordinary damping isolation often have performance limitations. Low-frequency resonances of buildings, sub-micron-level micro-vibrations on the ground, and weak disturbances from air currents - these low-frequency and highly penetrating disturbances are the pain points that conventional isolation platforms cannot completely filter out. They can easily cause interference fringes to drift, blur nano-imaging, cause spot jitter, and result in poor experimental repeatability, directly blocking the precision bottleneck of high-end scientific research.
To meet the demanding needs for ultra-stable frequency and extremely low disturbance in high-end scientific research, Saifan Optoelectronics has launched the air-floating isolation optical platform. Based on advanced air spring air-floating isolation technology, it breaks through the limitations of traditional damping isolation and achieves ultra-low natural frequencies, all-directional wide-band isolation, and automatic balance and leveling. It is specifically designed for cutting-edge experiments that are extremely sensitive to vibration, maintaining a stable baseline of nanometer-level precision.
The principle of air-floating suspension isolation overcomes the problem of low-frequency vibrations
Unlike the passive vibration reduction mode of traditional solid-state damping, the Saifan air-floating isolation optical platform adopts a precise air spring suspension isolation architecture. It forms a uniform suspended air film through a stable pressure chamber, replacing the traditional solid-state support with "air elasticity support without rigid contact". This fundamentally weakens the vibration transmission path. The platform achieves vertical 1–2Hz and horizontal 1–1.7Hz ultra-low natural frequencies, far below the conventional vibration frequency range in building environments. It perfectly avoids the low-frequency resonance trap and completely solves the problem of low-frequency micro-disturbances that damping platforms struggle to handle.
With an optimized air path damping and horizontal decoupling structure, the equipment can achieve efficient isolation in both vertical and horizontal directions. The 5–10Hz regular disturbance isolation efficiency can reach over 98%. It can quickly attenuate and filter out the most challenging low-frequency micro-vibrations, equipment resonances, pedestrian ground tremors, and air flow disturbances in the laboratory. It can quickly reduce and filter out disturbances, keeping the tabletop in an almost absolutely static suspended state. Even when subjected to instantaneous external force disturbances, it can quickly reset and level itself, without any residual vibration or drift, ensuring the stability of the experiment throughout.
Fully automatic intelligent leveling, self-adaptive stable pressure
Precision experiments often face issues such as equipment addition or removal, uneven load distribution, and center of gravity shift, which can easily cause the tabletop to tilt and the optical path to shift. The Saifan air-floating isolation platform is equipped with a high-precision pneumatic automatic leveling control system, featuring precise pressure regulating valves and highly sensitive sensing modules. It can monitor the tabletop levelness 24/7.
Whether it is adding optical components, heavy precision equipment, or changes in load center, the system can automatically adjust the air pressure at each support point, real-time correct the tabletop levelness, and throughout the process, there is no need for manual intervention or mechanical calibration. The stable pressure path operates smoothly, with constant air pressure, eliminating micro-vibrations caused by pressure fluctuations. It can maintain an ultra-stable state for long-term continuous experiments and 24/7 equipment standby, adapting to the long-term uninterrupted operation requirements of scientific research scenarios.
Honeycomb precision tabletop, high rigidity for precise optical path
The platform continues the high-end optical platform craftsmanship of Saifan, using a thickened all-steel honeycomb core composite structure, processed through overall stress elimination and precise leveling techniques. The overall rigidity is extremely strong, and its anti-deformation ability is outstanding. It does not collapse, deform, or have stress drift under heavy load conditions. The tabletop uses high-magnetic conductivity stainless steel finely ground plates, with excellent flatness, uniform and fine surface, wear-resistant, rust-proof, and free from optical pollution. It does not produce stray light reflection, suitable for ultra-high precision imaging, weak signal collection, and other demanding scenarios.
Global standard equidistant M6 threaded hole array, precise and highly consistent, can quickly fix various high-precision displacement tables, micro-systems, laser sources, interference components, etc., supporting the integration of complex large-scale optical paths, meeting the layout requirements of multiple devices, heavy loads, and high precision, and adapting to various high-end optical experimental schemes.
Extremely suitable for high-end scenarios, defining a new benchmark for precision isolation
With its ultra-low frequency vibration isolation, highly stable adaptive control, and zero residual vibration, the Saifan air-floating vibration isolation optical platform precisely fits the requirements of high-precision scenarios such as nanotechnology research, precise interference detection, super-resolution microscopic imaging, laser micro-nano processing, quantum optical experiments, and aerospace precision metrology. It is the core infrastructure for high-end laboratories to break through the upper limit of precision and improve the repeatability and data credibility of experiments.
Compared with imported similar equipment, this product has four advantages: high cost-effectiveness, short delivery time, local customization, and rapid after-sales service. The core air circuit components are precise and durable, the system requires no complex maintenance, and the operation is stable and reliable. It completely solves the pain points of expensive imported equipment, delayed maintenance, and long customization periods, helping to fully upgrade high-end precision optical experimental equipment to be fully domesticated.
With air as the medium and ultimate stable precision research
The ultimate competition in precision is ultimately the ultimate competition in stability. The Saifan optical electrical air-floating vibration isolation platform overcomes the problem of low-frequency vibration isolation with air-floating suspension technology, locks the nanometer-level steady state with intelligent voltage regulation and leveling, and ensures every ultra-high-precision experiment with domestic high-quality craftsmanship. It ensures no drift in the fine optical path, no deviation in each data set, and no obstacles in each scientific research breakthrough.
