BREVA- Precision positioning hexapods by Symétrie

Breva

HIGH ACCURACY ADJUSTMENT HEXAPOD

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.

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