When light reflects off a surface, not all of it reflects off at the same wavelength; some photons impart a portion of their ...

Color, as the way light's wavelength is perceived by the human eye, goes beyond a simple aesthetic element, containing important scientific information like a substance's composition or state.

Red laser light is coupled into a spectrometer chip with an optical fiber from the left. The light travels along the chip until it is scattered out the the top in a waveguide section on the right.

UC Davis electrical engineers have created a chip-sized device to measure the spectrum of visible and infrared light. The spectrometer-on-a-chip could have a wide range of applications in medicine, ...

Researchers have developed a compact, low-cost convolutional spectrometer that delivers lab-grade precision for applications ...
