Eulerian Cradle 512.51

The Eulerian cradle is a full-circle cradle with an assymetrical design. The Phi- and Chi-circle planes are at right angles to one another.

The motor and signal currents are transmitted via slip rings. This enables an unrestricted rotation around both axes.

A motorised XYZ-stage with an operational range of 150 x 150 x 25 mm is integrated in the Phi-circle.

For sample adjustment an optical microscope or an optional CCD-camera is integrated (see Accessories MiniVID).

All movements are equipped with zero-point controls, limit switches and step motors.

General Information:

The Eulerian cradles of the series 500 can be combined with the goniometers of the series 400 to create multi-circle diffractometers. These can be used for analytical investigations in the fields of X-ray and neutron diffraction.
