In top-level scientific research scenarios such as quantum optics, super-resolution microscopy, precise interference detection, laser micro-nano processing, and nano-lithography, the accuracy bottleneck often lies not in the equipment resolution, but in the dynamic environmental disturbances and load imbalance. Laboratory ground low-frequency resonance, air conditioning airflow tremors, personnel walking micro-disturbances, as well as changes in load center caused by adding or removing experimental devices and equipment relocation, and slight tilting of the tabletop, all can cause optical path drift, interference fringes jumping, and image blurring, distorting ultra-high-precision experimental data and reducing repeatability, greatly restricting breakthroughs in frontier scientific research.
To meet the strict requirements of ultra-low vibration tolerance, dynamic load adaptation, and full-scale horizontal stability for high-end experiments, Saifan Optoelectronics has dedicated itself to creating an automatic balancing air-floating isolation optical platform. Integrating ultra-low-frequency air-floating isolation technology and intelligent automatic leveling system, it breaks through the performance limitations of traditional damping platforms and ordinary air-floating platforms, achieving all-directional wide-band isolation, dynamic automatic leveling, and full-scale unmanned stable pressure throughout. With intelligent steady-state performance, it builds a core base for nanoscale precise experiments.
Intelligent automatic leveling system, dynamic adaptive full-scale stable pressure
Unlike the limitations of manual leveling and fixed stable pressure in conventional platforms, the Saifan automatic balancing air-floating platform is equipped with a high-precision intelligent pneumatic leveling control system, featuring high-sensitivity pressure sensing and precise stable pressure valve groups. It supports real-time dynamic monitoring and fully automatic adaptive leveling. During the experiment, regardless of adding optical devices, carrying heavy-load equipment, or load shift, or slight unevenness of the ground, the system can quickly sense the tabletop level deviation, independently adjust the air pressure of each supporting air chamber, and complete automatic correction and reset within milliseconds. The entire process requires no manual intervention or mechanical calibration.
The entire balancing system responds quickly and stabilizes pressure accurately, enabling large-range load adjustment and level correction, completely solving problems such as platform surface tilt, optical path deviation, and steady-state lag caused by load changes. Even in the event of instantaneous external force disturbances, it can quickly stabilize, without residual vibration or drift, maintaining the tabletop level stability for 24 hours, perfectly adapting to long-term, uninterrupted, and multi-conditioned high-end precision experimental needs, truly achieving one setup and full stability throughout.
Ultra-low-frequency air-floating isolation, all-directional filtering of subtle disturbances
The platform adopts a precise air spring suspension isolation architecture, replacing the traditional solid-state damping structure with an air film without rigid contact support. This cuts off the vibration transmission path at its source. With a 1–2Hz ultra-low natural frequency design, it precisely avoids low-frequency resonance interference from buildings and successfully overcomes the low-frequency micro-disturbance problems that conventional isolation equipment cannot handle. Combined with optimized horizontal decoupling and air path damping structures, it achieves efficient vertical and horizontal two-way isolation. The isolation efficiency for 5–10Hz environmental disturbances is over 98%, fully filtering ground micro-vibrations, equipment resonance, air flow tremors, and other types of interference.
Compared to passive damping isolation platforms, air-floating suspension isolation has no mechanical friction, no secondary vibration, no energy consumption, and no frequent maintenance. Combined with intelligent automatic leveling capabilities, it combines the ultimate isolation and anti-shake + dynamic horizontal stability dual core performance, keeping complex optical path systems in an almost absolutely static working state, significantly improving the accuracy and repeatability of experimental data.
High-stiffness honeycomb tabletop, heavy-load compatible with precise optical path integration
Continuing the precision standard of Saifan's entire series of high-end optical platforms, the tabletop uses a thickened all-steel honeycomb core composite structure, processed through professional stress elimination and precise leveling techniques. The overall rigidity is outstanding, and the anti-deformation performance is excellent. Under long-term heavy-load conditions, it does not collapse, does not deform, and has no stress drift. The surface layer uses a high-magnetic conductivity stainless steel finely ground sheet, with extremely high flatness, fine wear resistance, rust and corrosion resistance, no stray light reflection or optical pollution, and is suitable for ultra-precise imaging, weak signal acquisition, and other strict experimental scenarios.
The tabletop is equipped with a uniform M6 standard threaded hole array throughout the surface. The hole positions are precise and evenly distributed, with excellent adaptability. It can quickly fix various high-precision displacement tables, microscopes, laser light sources, interference components and other precision equipment, flexibly building large, complex and heavy-load optical optical paths, and fully meeting the system integration and diversified experimental layout requirements of high-end scientific research projects.
Full-scenario high-end compatibility, domestic precision engineering replacing imported products
With the core advantages of intelligent automatic balance, ultra-low frequency vibration isolation, high stability and heavy-load capacity, and no need for on-duty operation, the product precisely adapts to top-level high-precision scenarios such as quantum optical research, super-resolution microscopic imaging, precise interference detection, laser micro-nano processing, nano-precision measurement, and aerospace and aviation supporting experiments. It is the core precision infrastructure for high-end key laboratories and breakthroughs in precision limits of frontier scientific research projects.
Compared with the performance of similar imported equipment, the Saifan automatic balance air-floating vibration isolation optical platform, relying on the advantages of local independent research and development and production, has four major advantages: high cost performance, rapid delivery, flexible customization, and rapid after-sales service. The core air circuit and balance control system are stable and durable, requiring no complex maintenance on a daily basis, completely solving the pain points of high-priced imported equipment, long delivery cycle, delayed after-sales response, and high customization difficulty, and helping high-end optical experimental equipment achieve comprehensive domestication and upgrading.
Smart balance control, stable state, air-floating silent protection of precision
The precision competition in high-end research begins with stability and surpasses constancy. The Saifan Optoelectronics automatic balance air-floating vibration isolation optical platform solves the problem of dynamic imbalance with intelligent automatic balance technology, locks the nanometer-level steady state with ultra-low frequency air-floating vibration isolation, and uses the core strength of domestic precision engineering to protect each ultra-high-precision experiment, making the optical path stable for a long time, data precise and controllable, and scientific research breakthroughs without boundaries.
