In optical precision measurement and laser interferometry, even minute vibrations can cause significant measurement errors. Air-float vibration isolation optical tables have become essential equipment in high-end optical laboratories thanks to their ultra-low natural frequency and high isolation efficiency—the modern standard for precision laboratory vibration isolation.
The core lies in air springs combined with multi-hole quasi-laminar damping technology. Pressurized air creates a thin film cushion beneath the table, fundamentally cutting off vibration transmission from the floor to the surface. Multi-hole damping provides precise airflow resistance, preventing sustained oscillation and enabling rapid, smooth vibration attenuation.
The ZDT-P Series air-float vibration isolation optical tables employ air springs with ultra-thin composite bellows, achieving vertical and horizontal natural frequencies of 1.0-2.0Hz. Combined with multi-hole quasi-laminar damping, the ZDT-P Series delivers up to 95% isolation efficiency—significantly outperforming conventional rubber isolation, making it a top-tier laboratory vibration isolation solution.

The ZDT-P is equipped with a pneumatic auto-leveling system supporting plus/minus 10mm height adjustment, paired with a silent air compressor (below 50dB), enabling rapid table leveling without disturbing the experimental environment.
The ZDT-P Series achieves flatness of 0.05-0.1mm/m2 with a matte surface finish and roughness of only 0.8-1.6 micrometers—the professional standard for air-float vibration isolation optical tables, reliably supporting optical components while avoiding reflection interference.
The ZDT-P Series air-float vibration isolation optical tables are widely used in laser interferometry, holographic imaging, spectral analysis, precision optical path alignment, and microscopic imaging system integration—an ideal choice for precision optical laboratories seeking ultra-stable measurement environments.
Selection should consider total instrument weight, laboratory space, and optical path height requirements. The ZDT-P Series offers multiple size specifications with flexibly adjustable configurations. For higher load capacity and stronger shock resistance, LeadTop LHV Series Active Isolation Modules featuring air spring plus single-pendulum decoupling with 0.5-20Hz transmissibility -30dB or lower are also excellent laboratory vibration isolation alternatives.
