6.3 Alignment of the Diffractometer If a calibration check reveals significant errors in alignment (20 errors generally greater than 0.020 2e), an alignment of the diffractometer should be performed. If only some aspects of the Instrument have been modified, only an …

The laboratory X-ray powder diffractometer is one of the primary analytical tools in materials science. It is applicable to nearly any crystalline material, and with advanced data analysis methods, it can provide a wealth of information concerning sample character.

Freiberg Instruments manufactures diffractometers and automated in-line solutions for crystal lattice orientation and sample alignment. We specialize in the ultra-fast and precise Omega-scan method that allows determination of the complete crystal orientation in a few seconds.

crystal diffractometer, and there is a requirement for fast and reliable alignment techniques, preferably for computer control. This paper describes methods for simple and fast alignment of both crystals, so that the investigation of different reflections of a particular crystal, studies with

Proper alignment of an X-ray diffractometer is critical to performing credible measure-ments, particularly for residual stress determinations. This article will emphasize practical as-pects of diffractometer alignment and standards usage with regards to residual strain mea-surement.

Advantages of this method are the relatively simple diffractometer alignment and its flexibility. The disadvantages are the rather long measurement time (some minutes) and the problem of finding enough reflections. Successful Theta Scans on at least two different lattice planes are needed to determine the complete crystal orientation.

The Desktop X-ray Diffractometer for Crystal Orientation Measurement (DDCOM) is an automated tool to determine the orientation of various crystals using the Omega-scan method.

The Omega/Theta was designed for manufacturers. It’s ideal for the ultra-fast orientation and alignment of various crystal types in production, for marking in-plane directions, or checking the orientation of flats or notches. It is also ideal for production quality control, thanks to its high throughput speeds and automation capabilities.
