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). Max Theodor Felix von Laue (German: maks fn la 9 October 1879 24 April 1960) was a German physicist who received the Nobel Prize in Physics in 1914 for his discovery of the diffraction of X-rays by crystals. 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.įor more advanced applications, Proto can create custom saw-cutting adapters that can be utilized in the Laue-COS. The second is so that the point-group symmetry of the data can be interpreted since this provides part of the information that. The first is so that the symmetry of atoms and molecules in a crystal structure can be understood. The diffractometer can be configured with either a manual or motorized x,y stage for scanning across a crystal face or orientation mapping. There are two fundamental reasons for learning about point-group symmetry in crystallography. Equipped with a Proto tungsten x-ray tube, the system delivers on quality and performance, as well as convenient warranty/support options. Flexibility and Safetyīecause 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. An optional transmission camera is also available for weakly diffracting materials. Binning capabilities help ensure quick collection times, making Laue orientation as efficient as possible. With low noise, a pixel size of 64 by 64 microns, and a 150-by-100-mm area, images are produced with incredible quality. It is a small-size program but has convenient and straightforward graphic user interfaces (GUIs), with which one can quickly simulate a complicated Laue pattern only with a few mouse clicks. The camera is sensitive to a broad range of energies (4-60 keV). The LauePt computer program is an interactive Windows app for simulating white-beam X-ray Laue patterns of general crystals. They are named after physicist Max von Laue (18791960). This method uses monochromatic x-rays, but instead of studying a large single crystal it studies a powdera collection of many many microscopic crystals oriented in random directions. In crystallography and solid state physics, the Laue equations relate incoming waves to outgoing waves in the process of elastic scattering, where the photon energy or light temporal frequency does not change upon scattering by a crystal lattice. The OrientExpress program for Laue indexing Measuring the Laue peak coordinates Indexing the Laue pattern & crystal orientation Refining the fit to the Laue. The system features a back-reflection camera with high quantum efficiency that is made in house by Proto. called the Laue method, and it is frequently used to find the orientation of single crystal specimens. The difference in path lengths is indicated by the dashed line.Superior Image Quality for Accurate Single-Crystal Orientation Two incident waves reflect off two planes of a crystal.
