Researchers push the boundaries of optical microscopy

The field of optical microscopy research has developed rapidly in recent years. Thanks to the invention of a technique called super-resolution fluorescence microscopy, it has recently become possible to view even the smaller ...

Examining a nanocrystal that shines on and off indefinitely

In 2021, lanthanide-doped nanoparticles made waves—or rather, an avalanche—when Changwan Lee, then a Ph.D. student in Jim Schuck's lab at Columbia Engineering, set off an extreme light-producing chain reaction from ultrasmall ...

Creating the world's largest SiC aspherical mirror

Aspherical components in optical systems can increase the free design variables without introducing new aberrations. That brings improved imaging quality and reduced size and weight. Aspheric components are widely used in ...

May the force be with you: Detecting ultrafast light by its force

A McGill research team has developed a new technique to detect nano-sized imperfections in materials. They believe this discovery will lead to improvements in the optical detectors used in a wide range of technologies, from ...

New X-ray tool proves timing is everything

(Phys.org)—With SLAC's Linac Coherent Light Source X-ray laser, timing is everything. Its pulses are designed to explore atomic-scale processes that are measured in femtoseconds, or quadrillionths of a second. Determining ...
