The SH2 provides one axis of rotation about the centre of the manipulator and the second at 90° known as azimuthal rotation.
Two different offset positions available;
- a) The SH2E50 will provide move the sample away from the centre axis,
- b) The SH2R64 moves the sample position 64mm above the central axis.
As with all the manipulation range, this module is fully compatible for both the heating and cooling modules making it the perfect multidiscipline two axis sample mounting module.
Note: totally non-magnetic version are available.
