change is a ‘must-have’ feature in their decision to invest in an XRD system.”


For many users, powder samples are their primary interest and here Empyrean delivers the highest accuracy and data quality in the most flexible and advanced system on the market. Switching to thin films, Empyrean provides for high-resolution epitaxy analysis and handles all common applications. Investigations into nanomaterials can also be performed with Empyrean: size and shape of crystalline domains within the material, and structural analysis of near amorphous materials are all possible. PDF (pair distribution function), SAXS (small angle X-ray scattering), and even the ability to monitor the evolution of crystalline phases in situ with the unique slurry flow cell stage are all possible on the advanced Empyrean platform. Finally, the internal structure of solid objects can be studied without having to be cut: the unique PIXcel3D detector can be used as a CT scanner allowing non-destructive analysis of pharmaceutical formulations (tablets, capsules), electronic components (batteries, ICs, capacitors) and geo- and archaeological samples, to name a few.


LedEngin’s LED 10W and 40W Emitters offer multiple possibilities 2010-06-24


LedEngin will showcase its Multi-Color and White High-Power LEDs at Guangzhou International Lighting Exposition in China.


LedEngin, a solid-state lighting company specializing in high brightness LEDs, is introducing a 15W, 4-die (7mm x 7mm) package and a 40W, 12-die (9mm x 9mm) package. Available in RGB, RGBA, RGB-White multi-color LEDs and a full range of white LEDs, color temperatures range from 2700K to 6500K.


The CTE-matched materials and patented packaging technologies are chosen to optimize light output and minimize stresses resulting in color point stability and lumen maintenance well beyond industry standards.


The thermal resistance of 1.8° and 0.7° C/W respectively, allows industry highest power density from such small, high flux density light source, are essential for maximum flux in beam and “Lux on TargetTM”. The robust packaging allows the LEDs to meet JEDEC Level 1 Moisture Sensitivity Levels for unlimited product floor life. The robust product design thrives in outdoor applications with high ambient temperatures and high humidity.


“We are able to do this with superior uniformity across the beam and without compromising on the brilliance of the light.”

The 4-die and 12-die multi-color LEDs are claimed to provide a brilliance of colors across the entire color spectrum with outstanding color mixing and uncompromising performance. The ability to configure multiple red, green, blue (RGB) high-brightness die within a very small package creates superior, flexible in-source color-mixing due to dramatically reduced mixing heights, ideal for architectural, decorative and entertainment lighting applications.
