An optical spectrometer is an instrument used to measure properties of light over a specific portion of the light spectrum. These devices have found a wide range of practical applications. Dispersive ...

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, ...

Mass spectrometry is already a powerful tool for determining what kind and how many molecules are present in a given sample. But most instruments still analyze their molecules one or just a few at a ...

Researchers 3D printed a miniature ionizer, a key component of a mass spectrometer. Their device could someday enable an affordable, in-home mass spectrometer for health monitoring. Mass spectrometry, ...

Meet the world’s smallest optical spectrometer. Crafted from a single nanowire less than 100 µm long, the device can measure the intensity of colored light across the visible spectrum and may ...

Samsung is a manufacturer that acts at 360° in the world of technology. And one of the aspects in which it is most active is certainly that of mobile devices. Its innovation comes mainly from the ...

[Project 326] wanted to know exactly what gas was in some glass tubes. The answer, of course, is to use a spectrometer, but that’s an expensive piece of gear, right? Not really. Sure, these cheap ...
