For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food ...

Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the ...

For decades, bulky spectrometers have been the main tools for understanding how things are made of chemicals (a thing called ...

“Spectrometers are critical tools for helping us understand the chemical and physical properties of various materials based on how light changes when it interacts with those materials,” says Brendan O ...

ABERDEEN PROVING GROUND, Md. — U.S. Army Combat Capabilities Development Command Chemical Biological Center researchers are developing a way to scan for chemical biological agent on surfaces on the ...

Before a spectrometer can do any useful work, it needs to be calibrated to identify wavelengths correctly. This is usually done by detecting several characteristic peaks or dips in a well-known light ...
