bearing based goniometer for Φ-positioning

The ECGp5050 provides high-resolution Φ-positioning over a 10° range. Combined with the ECGt5050, the ECGp5050 forms the lower positioner of a powerful Euler Goniometer with a common center of rotation. It can be combined with a xy-stack of ECSx5050 to add two more degrees of freedom to the motion of the sample.
The positioner is designed for ultra-high vacuum with pressures down to 1E-9 mbar (/UHV), all positioners can be baked out up to 150°C .
Stainless steel is a rugged, cost effective material for the nanopositioner body that is compatible with demanding vacuum conditions up to UHV.
