PRECISION POSITIONING HEXAPOD WITH HIGH STABILITY

JORAN hexapod is a high precision system designed to position and adjust elements with a 0.5 µrad angular resolution.

The conception of JORAN, particularly of its actuators, spherical joints and natural granite platforms, ensures great stability and guarantees the positioning quality over time.

Ceramic spherical joints can be replaced by universal joints if the angular travel range is too large or if external forces are too big.

Developed in collaboration with the European Synchrotron ESRF, it is ideal to support mirrors or vacuum chambers on synchrotrons beamlines.

Granite platforms can be replaced by steel platforms if preferred.
