linear bearing based nanopositioner for horizontal motion

The ECSx5050 is the positioner with the largest footprint of attocube's Industrial Line. It provides high-resolution positioning over a travel range of 30 mm. For xyz-positioning, two ECSx5050 positioners can be mounted on top of each other and combined with a third one attached to an L-bracket. Its high accuracy is achieved with crossed roller bearings.
Stainless steel is a rugged, cost effective material for the nanopositioner body that is compatible with demanding vacuum conditions up to UHV.
