Multiwire Laboratories, Ltd.

ScanORIENT™ provides:

• Simple data entry from 4" x 5" (9 x 12 cm) Polaroid™ films
• Quickly indexes back-reflection Laue patterns of cubic, hexagonal, and triclinic systems. Ideal for crystals of silicon, gallium arsenide, sapphire, quartz, SiC, nickel, tungsten, turbine blades, as well as geological minerals such as olivine, etc.
• Generates stereographic projections from indexed Laue pattern
• Minimal instruction time necessary to achieve unique orientation solutions
• Ideal for academic teaching laboratories or for industrial research applications

A Short Tour...

1) Scan the Laue back-reflection film

First collect a back-reflection Laue photo. Place the Polaroid™ image on TWAIN compatible scanner connected to a PC computer and scan it into ScanORIENT™ program. Enter parameters (film-to-specimen distance, sample name, indexing file name, etc.). Enter the position of 4 to 8 Laue spots into the ScanORIENT™ program by manually positioning cursor over spot and left clicking on mouse. A minimum of 4 spots must usually be entered to obtain a unique solution. (The first two spots must be low index spots and in the indexing table - the Miller index of all the other spots entered are computed by the program.)

2) Verify / Configure the Parameters

3) Index the Laue pattern

The ScanORIENT™ program generates an analysis of the planes (spots) entered. The program compares the experimentally observed angle between the first two spots with a table of angles. It calculates the HKL of the other spots based on a trial orientation matrix. If a self consistent solution is found, the spots are indexed. Maximum Miller index for the program is 15.

4) Request a Stereographic Projection

A stereographic projection (with 3 or 4 Miller indices) can be generated from the current indexed photograph or from a reference orientation (called stand-alone). A "Move-To" feature is available to compute the angular rotations necessary to bring any diffraction spot into its "oriented" position in the center of the plot or to determine the miscut of the crystal. Either rotation angles about three axes or any arbitrary HKL can be entered to rotate the orientation matrix to its new position. The stereographic image may be be printed.

5) Get a Report

The report displays the comparison made between the observed vs. calculated angles between planes (in degrees) for all of the spots initially entered. Gamma and delta are the horizontal and vertical rotation angles in degrees necessary to bring that particular plane into orientation (i.e. the center of the photograph). A printout of the report results along with the digitized Laue planes may be selected for record keeping purposes.

Additional Features:

• Can save, recall, and print images.
• Custom angle data generator produces data lists to your specific needs.
• A general cubic table of angles between planes is provided along with a sample pattern to get you started!

Computer and Scanner System Requirements:

• Pentium II, or higher order processor
• Windows 2000 or above
• 128+ Mbyte of memory
• VGA 24-bit color display
• 10 Mbytes of hard drive space
• CD-ROM drive
• Printer or USB port for HASP security device

You will also need a TWAIN-compliant scanner (e.g. an Hewlett Packard Scanjet 5300 series), installed and operational. Note: a flat-bed scanner with a resolution of greater than 100 dpi and capable of 256 levels is preferred.
