Utilizing modern, cutting-edge technology, Proto® developed the Laue-COS system to offer a convenient solution for orienting single-crystal materials such as scintillation crystals, non-linear optics, piezoelectrics, minerals, and substrates. Producing research-quality data with impressive speed, this turn-key system features the latest in digital technology and an assortment of advanced feature options to ensure easy and efficient collection.

The Laue-COS is a self-contained instrument that does not use any consumables (e.g., detector gases), and it enables experiments on versatile samples, geometries, and crystal systems. From small crystals to heavy boules and rods, this Laue orientation system provides a unique solution for a wide range of applications.

Laue-COS Diffractometer

Superior Image Quality for Accurate Single-Crystal Orientation

The system features a back-reflection camera with high quantum efficiency that is made in house by Proto. The camera is sensitive to a broad range of energies (4-60 keV). With low noise, a pixel size of 64 by 64 microns, and a 150-by-100-mm area, images are produced with incredible quality. Binning capabilities help ensure quick collection times, making Laue orientation as efficient as possible. An optional transmission camera is also available for weakly diffracting materials.

Flexibility and Safety

Because it is housed in a large cabinet, the Laue-COS system enables the measurement of large parts and the incorporation of additional accessories while providing full radiation protection for users. Equipped with a Proto tungsten x-ray tube, the system delivers on quality and performance, as well as convenient warranty/support options.

Customization Options

The diffractometer can be configured with either a manual or motorized x,y stage for scanning across a crystal face or orientation mapping. When it comes to orienting the crystal for cutting or quickly scanning the crystal to identify reflections, manual or automated goniometers with chi, phi, and omega rotation are both available to best suit your experimental needs.

For more advanced applications, Proto can create custom saw-cutting adapters that can be utilized in the Laue-COS. Finally, Proto’s software package covers both collection and in-depth analysis, including support for all crystal systems and integration with the Crystallography Open Database (COD).
