We are seeking to procure two high-precision optical tables, each measuring 120 cm x 150 cm. The required units must feature a sealed hole design to ensure surface cleanliness and protection of the internal honeycomb structure. Furthermore, the tables must be equipped with an active damping system, specifically an integrated frame-type vibration isolation mechanism, supported by single-leg configurations. All submitted proposals must guarantee compatibility with high-sensitivity optical experiments and include full technical documentation regarding load capacity and vibration attenuation performance.
