Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and ...

Researchers have built a paper-thin chip that converts infrared light into visible light and directs it precisely, all without mechanical motion. The design overcomes a long-standing efficiency-versus ...

The invention of tiny devices capable of precisely controlling the direction and behavior of light is essential to the ...

Metasurfaces in which nonlocal light-matter interactions take place are a potentially useful variant of traditional ...

The human eye can only see light at certain frequencies (called the visible spectrum), the lowest of which constitutes red light. Infrared light, which we can’t see, has an even lower frequency than ...

They found that mice wearing the lenses chose to avoid a box flooded with infrared light, instead choosing to move to a completely dark box. But mice who weren't wearing the lenses didn't show a ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
