The NorthStar v6.0 software indexes cubic, hexagonal, ....triclinic crystal systems, and creates stereographic projections.  Provides accuracy of 0.25 degrees in standard mode and 0.05 degrees in high-resolution mode.  Operates best with the MWL motorized orientation stages. 

Ideal for industrial process control, research application or academic laboratories. Utilize the real-time detector, motorized orientation stages, and computer analysis of back-reflection images to quickly characterize or determine the orientation of the lattice planes in a variety of crystal materials such as silicon, gallium arsenide, sapphire, and geological minerals.

The NorthStar v6.0 software automatically collects, find peaks, and indexes most back-reflection Laue images. "Find extra planes" feature now even shows you the computed plane position oriented behind the collimator that you can't see when perfectly oriented! Version 6 software is the culmination of several years of development work and is a quantum improvement over any other available Laue software, especially in the area of ease of use.

The software a) accommodates small variation in film-to-specimen distance, b) controls percentage of Laue spots to be indexed (can now ignore a few troublesome points, if needed), c) tries multiple combinations of starting Laue points and selects the best orientation matrix automatically, and d) has new "speed icons" for faster manual work and new "macro" facility for one-touch analysis of crystal orientation.

Once set with the right conditions, Novice users can achieve Expert results quickly with very little effort.

NorthStar v6 software software automatically detected 22 spots in the image and indexed the Laue image. The Find Extra Planes feature has been turned on for 111 plane (shown in green circle) so that misorientation statistics are give below the indexed image (The 111 plane is 8.9 degrees out from the center, 8.8 degrees to the left and 1.1 degrees up in rectangular coordinates).  A stereographic projection of this orientation is given on the right.  The red spots are the hkls (Miller indices) in the Laue image that also appear in the stereographic projection.

Total time to collect and analyze a Laue pattern? About 6 seconds (5 seconds for Laue image, 1 second analysis time).
