(Nanowerk News) Researchers have shown that newly designed pixel-scale metasurface lenses — flat surfaces that use nanostructures to manipulate light — can be used to make imaging sensors that are ...

Suited for use in sorting or matching reflective surfaces by color, the small-footprint (1.08 x 0.843 x 0.355-in.) OPB780 reflective color sensing assembly uses an 8 x 8 photodiode array to provide ...
