RFP Optical Tables

The SFU Quantum Internet Systems Lab (QIS-Lab) led by Canada Excellence Research Chair (CERC) Prof. Thomas Jennewein requires highly stable optical tables that will house the optical setups on a very stable and vibration-stabilized platform. This includes four (4) optical tables, which are levitated on isolating cylinders with compressed air. These are required to prove a stable platform to implement photonic setups that often require interferometric stability. Basic Specifications Four optical tables with surface area of greater than 4.0 m^2, and thickness of around 0.3m. Acceptable dimensions are 1200 x 4000 x 305 mm^3, or 1500 x 3600 x 305 mm^3. Maximum length is 4200.00 mm Metric format (typically with M6 threaded mounting holes, 25mm spacing) Four active air isolation legs. Low vibration and stable for quantum optics, single-photon experiments, interferometry, and precision laser/optical alignment. High static rigidity and low dynamic compliance. Top Surface: Stainless steel, corrosion resistant, with matte/brushed low-reflectivity finish. Bottom surface: Steel or stainless-steel skin with construction selected to provide thermal symmetry between the top and bottom surfaces. Thermally symmetric / athermalized construction: Top and bottom structural skins should have matched or closely matched coefficients of thermal expansion to minimize table bowing during changes in laboratory temperature. This approach is used commercially specifically to reduce thermally induced bow. Surface flatness: ≤ ±0.10 mm over any 600 mm × 600 mm area, or better. Support system should accommodate the complete table mass plus at least 500 kg distributed experimental payload, with appropriate safety margin. Vendor must state maximum permissible distributed and concentrated loads. Construction and bonding processes should minimize residual mechanical and thermal stresses and avoid long-term warping or delamination.
