ECGt5050/StSt/NUM+/UHV
bearing based goniometer for Θ-positioning
The ECGt5050 provides high resolution Θ-positioning over a 10° range. Combined with the ECGp5050, the ECGt5050 forms the upper 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 5E-11 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.
