This Thorlabs product leaflet provides specifications, dimensions, performance data, and construction details for Nexus optical tables and active isolator…
The Nexus series offers optical tables and breadboards in sizes from 4' × 6' to 4.8' × 10' with 210 mm or 310 mm thicknesses. All‑steel construction, a precision‑machined matte finish, and a honeycomb core give excellent thermal stability and flatness. Each table ships with active pneumatic isolator legs (600 mm or 700 mm tall) that isolate vibrations from 3 Hz to 50 Hz.
Technical data include table thickness, flatness, mounting‑hole pattern, dynamic deflection coefficients, resonant frequencies, load capacity, and height‑adjustment range. Optional sealed mounting holes and anti‑static packaging are available. Every unit is tested and supplied with a unique test‑data certificate and compliance curve.
