NIMES, France, Nov. 19, 2015 — Symétrie has announced the ZONDA hexapod for applications such as space optics that require precision positioning, heavy loads and long travel ranges. Designed to position payloads up to 400 kg with a resolution of 50 nm, the device offers travel ranges of 400 mm in XY, 300 mm in Z and 40° in Rx, Ry and Rz rotations. Accuracy and thermal stability are ensured through the use of Invar material, linear absolute encoders and rigid joints. Invar is an alloy of iron and nickel, known for its very low coefficient of thermal expansion of 1 μm/m/°C. ZONDA can be vacuum- or cleanroom-compatible.
