Eulerian Cradle 511.5

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.

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 the Phi-axis.

A manual Z-adjustment 5104.A05 is integrated in the Phi-circle, enabling the mounting of goniometer heads.

Incorporated in the Chi-circle is an aperture of 90mm. This limits the operational range to 157°.

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

Both circles are equipped with zero-point controls and step motors. A range of different motor types and specifications is available according to customer requirements.

In combination with the 2-Circle Goniometer 424 this system forms a compact X-ray diffractometer.
