ROBERTSBRIDGE, England, May 5, 2008 -- Photonic Science Ltd. said its new generation of detectors -- Laue microdiffraction and backscattered cameras -- are designed for laboratories and synchrotrons wanting to carry out systematic bulk crystal orientation and microcrystal characterization.

The cameras allow unique backscattered geometry with collection time varying from near real time to a few minutes, depending on source, detector and crystal combination. Automated sample rotation, combined with shutterless acquisition, brings simpler and more flexible data collection routines, the company said.

The x-ray Laue camera works with a 2-µm pink beam size at the European Synchrotron Radiation Facility, Photonic Science said.

The acquisition software delivers ready-to-be-indexed digital images. Useful online tools such as angle, intensity and profile measurements are available from either a laptop or desktop computer. Indexation of Laue patterns can be performed offline using dedicated software packages.

Existing Laue setup can be upgraded with turnkey solution including beam delivery to detector installation. Very high resolution detectors allowing strain analysis studies are available on demand.

Its new Laue camera dubbed Cyclops is a neutron CCD detector, Photonic Science said, with applications including: real-time magnetic/structure transitions, photo-induced transitions, stroboscopic crystallography, modulated and incommensurate phases, very small single crystals, and high pressure physics.

Key features include:
  • An octogonal array of neutron scintillators
  • X16 image-intensified cooled CCD cameras
  • 20 megapixels, 160 x 160 microresolution
  • 70 percent of 4p with subsecond read-out
  • Focusing supermirror thermal guide
  • Real-time reciprocal space surveys
Photonic Science said it will be exhibiting the cameras at the Denver X-ray Conference, Aug. 4-8, 2008.

GLOSSARY
backscatter
The deflection of radiation by scattering processes through angles that exceed 90° with respect to the original direction of motion.
beam
1. A bundle of light rays that may be parallel, converging or diverging. 2. A concentrated, unidirectional stream of particles. 3. A concentrated, unidirectional flow of electromagnetic waves.
camera
A light-tight box that receives light from an object or scene and focuses it to form an image on a light-sensitive material or a detector. The camera generally contains a lens of variable aperture and a shutter of variable speed to precisely control the exposure. In an electronic imaging system, the camera does not use chemical means to store the image, but takes advantage of the sensitivity of various detectors to different bands of the electromagnetic spectrum. These sensors are transducers...
crystal
A solid with a structure that exhibits a basically symmetrical and geometrical arrangement. A crystal may already possess this structure, or it may acquire it through mechanical means. More than 50 chemical substances are important to the optical industry in crystal form. Large single crystals often are used because of their transparency in different spectral regions. However, as some single crystals are very brittle and liable to split under strain, attempts have been made to grind them very...
detector
1. A device designed to convert the energy of incident radiation into another form for the determination of the presence of the radiation. The device may function by electrical, photographic or visual means. 2. A device that provides an electric output that is a useful measure of the radiation that is incident on the device.
microcrystal
A microscopic crystal found in an intricately crystallized substance that is only visible under a microscope.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
synchrotron
A device that uses superconducting magnets to bend or accelerate charged particles. It can be used to etch very fine high-density patterns on integrated circuits.
