Real-time Laue Single Crystal Orientation Tool

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.

  • Real-time Crystal Orientation down to 0.2 degree
  • Misalignment measurement down to 0.02 degree
  • Laue Indexation software
  • Turnkey solution, custom upgrade for existing system

Cooled InGaAs camera for SWIR imaging

SWIR imaging

In the last few years a whole new waveband of the electromagnetic spectrum has been opened up for exploitation: the Short Wave Infra Red (SWIR). The band runs from the edge of the near IR region at 900 nm up to 1700 nm, and has traditionally been invisible to all detectors. Now, Indium Gallium Arsenide sensors can image within this waveband, for a wide range of applications. For example, solar cells can be made to emit in this waveband, allowing in-line inspection of their internal structure during manufacture. Bruising of fruit can be detected by imaging the sub-surface accumulation of water. Surveillance applications can benefit from reduced atmospheric scattering due to mist in the SWIR band, and can take advantage of the SWIR band “night glow” of a clear night sky. SWIR band laser illuminators, invisible to most detectors, can provide high quality night vision when coupled with a SWIR camera.

Silicon wafer inspection with laser induced photoluminescence

Photoluminescence wafer inspection system

Solar cell / bare wafer photoluminescence inspection system
Photoluminescence (PL) performs non contact testing of PV cells and wafers by using a laser source. PL images are captured with a cooled InGaAs camera within 100ms exposure depending on source power used. PL imaging (proportional to minority carrier life time which correlates with cell efficiency) can be performed at any point of solar cell processing (bare wafer, wafer with oxide or nitride, patterned finished cell)

The on line testing solution is capable of very high throughput up to 3,600 wafers / cells per hour.

Intuitive software detects micro cracks, shunts, hot spots and low efficiency areas
  • Bare wafer in line inspection
  • Processed cell in line inspection
  • Finished panel inspection (installed panels / prior to installation)

Laue Neutron & X-Ray System

High resolution Laue Neutron & X-ray imaging system — the dual camera system allows a digital backscattered Laue diffraction pattern to be recorded, with a resolution of 2080x1392 pixels and 12-bit digitisation at 10MHz. The X-ray beam passes through the camera in a straight lead lined tube of 16mm diameter, to protect the camera system from scattered X-rays. The image areas allow some overlap to permit image stitching and provide a single continuous image with an input dimension of 156mm x 104.4mm. The system is supplied in a unified housing with mounting plate. The x-ray scintillator screen is GdOS:Tb 0.1mm thick with a peak emission at 550nm to match peak QE response of the CCD. Other scintillators are available to order. The input scintillator is covered by a thin aluminium light exclusion window. The camera features a variety of functions such as binning, sub area readout and 16 bit acquisition mode, which apply to the single combined image.

PSL new microCT system unveils details down to 400nm

The instrument records a series of radiographs for different angular positions of bone, foams, composite, polymers down to sub micron resolution.

Continuous rotation allows acquisition of a full data set within minutes and 3D reconstruction to be performed on the fly thanks to massively parallel calculation on multi GPU machines.

Phase contrast edge enhancement technique can also be used for refining 3D tomographic reconstructions.
