Real time Laue CCD camera system for single and bulk crystal orientation

The single crystal Laue Orientation Tool uses a unique back scattered detector geometry and provides real time alignment facilities down to +/-0.02 degree accuracy. Configured for small crystals (horizontal setup) or bulk crystals / wafers (vertical setup), the system also allows mapping, scanning routines for texture analysis on polycrystalline samples. The Turnkey Digital Laue detector allows high throughput crystal characterisation with automatic sample positioning. Adaptors for saw cutting, for easy transfer of single crystals from the Laue system to a wire saw available.

The system enables real time crystal orientation by recording live digital backscattered LAUE diffraction patterns.

It allows very fine crystal alignment down to 0.2 degree accuracy using our standard Laue orientation tool.

0.02 degree misalignment can be measured using our microdiffraction set up.

Combined with motorised single crystal rotation / translation, the system brings simpler and more flexible ingot and raw crystal orientation routines before and after cutting / slicing procedures.

The system is delivered with a user friendly graphical user interface which will index diffraction patterns from known crystal structures.

An automatic software routine will derive orientation / misalignment of sapphire, silicon, YAG and other materials which undergo high throughput production.

The system comes as a tunrkey solution or as an upgrade to existing Polaroid Laue set up.
