High-Performance Pneumatic Vibration Isolation Marble Optical Table TTAS-2015M
JCOPTIX high-performance pneumatic-isolation marble tables use naturally aged premium stone with released internal stress and long-term deformation resistance. Precision grinding achieves grade 00 flatness and 0.63 μm roughness. Marble is naturally nonmagnetic, rust-resistant, and wear-resistant. Low thermal/load deformation gives high flatness, rigidity, reliability, and stability. Independent cylindrical pneumatic legs avoid overall resonance. Internal three-wire pendulums minimize vibration and precisely reposition tops after disturbance. Conventional laminar damping uses an orifice between primary/secondary chambers to compress/release gas for stability. Micrometer-scale damping replaces one chamber with many tiny holes, increasing efficiency and reducing amplitude. Hybrid chambers increase compliant volume within a given size and lower natural frequency. High-performance pneumatic marble tables. Models: TTAS-1008M, TTAS-1208M, TTAS-1510M, TTAS-1512M, TTAS-1812M, TTAS-2010M, TTAS-2012M, TTAS-2015M, TTAS-2412M. Flatness: grade 00. Roughness: 0.63 μm. Vibration criterion: VC-D. Vertical: 1-1.8 Hz; horizontal: 1-1.8 Hz, depending on load/use. JCOPTIX uses naturally aged Indian M10 stone with released stress, low thermal/load deformation, reliability, and stability. Precision grinding gives high flatness, low roughness, and wear resistance. Marble is weakly magnetic, nearly nonmagnetic, for sensitive settings. Three-wire pendulum legs use sensitive US-imported valve cores, automatic inflation/leveling, short response, and rapid balancing. Repositioning accuracy: ±0.05 mm. Isolation frequencies: vertical 1-1.8 Hz, horizontal 1-1.8 Hz, load/use dependent. Carbon-steel supports can be customized as weakly magnetic stainless legs. Float range: 0~20 mm. Vibration criterion: VC-D. 9 standard sizes are available. Tops weighing <2000 kg use 4 legs; ≥2000 kg use 6.
