Natural silicon’s indirect bandgap prevent its use, as is, in next-generation solar technologies. A team from the Carnegie Institution for Science has developed a new type of silicon using a quasi-direct bandgap that falls within the required range for solar absorption.

Laser “honeycombs” have enabled the simulation of theoretical materials with curious properties. By aligning multiple laser beams in such a way that they create standing waves with a hexagonal pattern, researchers in Zurich have been able to trap a group of potassium atoms cooled to near absolute zero inside a vacuum chamber. The potassium atoms demonstrated behavior similar to that of electrons in graphene.

Line Scan Cameras Enable High Speed Inspection of Color Filters Within Flat-Panel Display
Teledyne DALSA, Machine Vision OEM Components
The market of flat-panel displays (FPD) is a nearly $100 billion business that needs efficient automated optical inspection (AOI) to meet rising demand and remain cost effective. The color filters within the display represent a major inspection task, demanding both precision and speed. Inspection systems using high-speed, high-resolution line scan cameras have proven themselves both equal to the present need and able to support panel technology’s evolution.

FEATURED VIDEO
DataRay – BeamMap2
The patented BeamMap2 multi-plane scanning slit profiler uniquely speeds measurement and adjustment of focused and divergent laser beam assemblies, either as a standalone instrument, or interfaced to automated adjustment systems. This brief video describes the BeamMap2 operating principles and shows example measurements on actual focused and diverging beams.
