Photonics Spectra: March 2014

Manufacturers Refocus Technology Efforts Following Recent Financial Woes
Overcapacity has caused financial problems in the past few years, so the solar industry has been somewhat less focused on implementing technology advances - but today things are looking up and research is being rivived. The solar market was technology driven until 2012, but then experienced a collective tightening of belts as the industry went into overcapacity in 2012 and 2013. Much of...

Thanks for Stopping By!
Maybe you came for a meeting with a member of our team, or to tell our Light Matters newscast crew how you got your start in the industry. Perhaps you happened upon our Photonics Buyers’ Guide 60th-anniversary celebration, heard our president, Tom Laurin, speak about the company’s early days and then stayed for a piece of cake. Or maybe you came by to say a few words about one...

Lasers and Fake Corneas Connect Teens, STEM and Photonics
Learning middle school science from a textbook can be boring; at least it was for me! But it would have been less so if I could have constructed solar ovens, performed “simulated laser surgery” or seen photonic technologies at work in the real world. A special science program at North Carolina State University has found the secret to exciting kids and their teachers about STEM...

Tapping solar’s full potential
Solar cells may be a little closer to full realization of their potential, thanks to the creation of large sheets of nanotextured silicon microcell arrays. The discovery promises to make solar cells lightweight, bendable, more efficient and easily mass-produced. Converting sunshine into electricity is not a difficult process, although the lack of a national solar cell network reveals that...

Seeing the puck in strobe
The buzzer sounds. The crowds cheer. Twelve angry hockey players fly out onto the ice, blades clicking, to test their reflexes, brute force and balance. It’s pandemonium. Chaos. And in the middle of it all, each player is hunting for a tiny, wily puck. Any training tool that offers the upper hand is invaluable, even if it sounds counterintuitive. One such instrument is a piece of...
