414_414A

Standard version

2-Circle Goniometer 414/414A

The 2-Circle Goniometer 414/414A basically consists of two Goniometers 410 mounted one on top of the other.

The rotational axis of the lower circle (Theta) is fed through the upper circle (2-Theta) by a drive shaft.

This system, when mounted on a detector arm, is ideal for application as an analyser in 4- and 6-Circle Diffractometers.

  • four precision configurations
  • two load configurations
