CAMBRIDGE, England, Oct. 24, 2017 — A microscopic 'pen' has been developed that uses a commercially available printing technique to write nanostructures that are small enough to trap and harness light. The use of inkjet printing in nanophotonics has so far been limited by the coarse resolution of conventional printing methods. Researcher Vincenzo Pecunia at the University of Cambridge, whose work focuses on printable optoelectronic materials, obtained an electrohydrodynamic jet printer for his team. A chance meeting between Pecunia and researcher Frederic Brossard at the Hitachi Cambridge Laboratory led to the discovery...Read full articleRelated content from Photonics MediaARTICLESRetroreflective Material Helps Robots to Analyze SurroundingsA material developed and introduced by researchers at the University of Luxembourg will help robots analyze and understand their surroundings.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookLaser Safety: Important Considerations: Laser safety is nothing to scoff at; lasers can be hazardous. Enter Class 1 laser products — lasers that are so safe that the user doesn’t require specific laser safety training or protective eyewear. Some precautions still exist, though.When purchasing an industrial laser system, the astute buyer will look for a Class 1 laser product — a system where the laser beam hazard is completely enclosed and there is no potential laser...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookLaser Measurement Systems: Best Practices: When purchasing a laser, learning how to apply, troubleshoot, and evaluate that device is very important.Given the pace at which technology advances, there always seems to be a learning curve.
