Description

Details

BREVA hexapod has been specially designed to provide high angular accuracy. It allows angular positioning of objects like samples, probes or sensors with a resolution of 0.5 µm or 2.5 µrad.

It comes in 3 different versions depending on its motorization: DC, stepper or brushless motors.

BREVA hexapod can be used in any orientation: vertical, horizontal, upside down…

Applications

► Optics positioning without operator intervention

► Adjustment for assembly

► Sample micropositioning on diffractometer for synchtrotrons beamlines

► Microwave antennas testing
