| Focusing X-ray diffractometers working in
Bragg-Brentano geometry use a principle which is over 2000 years old - Euclid once proposed that in a circle, a cord will subtend equal
angles at points on the circumference, no matter where the points
are chosen. Since Parrish's proposition the diffraction principle has
changed very little. Powder diffractometers are generally reliable instruments capable
of producing good quality data for many years. However, due to the relatively
quick aging of the automation control electronics and software, they
became old fashioned and obsolete. Since goniometers
and their diffraction geometry have changed very little, they are easy to
upgrade. Several companies are producing hardware
and software for the automation and control of old diffractometers. |

Difftech 122D
Upgrades hardware and software for
old diffractometers to provide automation control and data acquisition.
Capabilities: driving theta/2theta coupled and
decoupled goniometers, automatic sample changers, single and multi pass,
data collection optimization. Suitable also for temperature stages, texture
and stress goniometers and multiple axes. The Difftech 122D provides
hardware control and is complemented with the Visual XRD software. |

DataBox
XRD control
Automation. Stepper motor control replaces obsolete
systems and/or automates manual diffractometers. The DataBox is complemented
with DataScan software which provides many useful
features, making it comparable with new diffractometer systems.
Capabilities: new
scan progress, multiple diffractometer support, multiple user support, improved support for Theta-Theta goniometers.
