Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of the utmost importance in applications ranging from environmental monitoring and ...

Optical frequency comb sources provide thousands of precise and accurate optical lines in a single device enabling the broadband and high-speed detection required in many applications. A main ...

Li-ion batteries are critical in energy storage, but their increasing energy density has led to worries about their safety.

A spectrometer is an imaging system used to map plurality of monochromatic images of the entrance slit onto the detector plane. This slit determines the amount of light (photon flux) that enters the ...

If you want to find out what something is made out of, you’ll probably be using a spectrometer. These devices allow scientists to determine what something is made of by shining light through an object ...

Spectrometers are widely used tools in chemical and biological sensing, materials analysis and light source characterization. The development of a high-resolution on-chip spectrometer could enable ...

Compact imaging spectrometer combines a catadioptric lens and a special flat immersion reflection grating. (Courtesy: Ronald B. Lockwood, MIT Lincoln Laboratory) A new, slimline imaging spectrometer ...

University of Illinois chemistry professor Alexander Scheeline has developed software that turns a camera phone, an LED, and a few other cheap tools into a spectrometer. Armed with these, he thinks we ...

As much as we know today about the planets of the solar system, it’s almost incomprehensible that a mere 50 years ago we knew almost nothing about them. Observations of even Mars and Venus, Earth’s ...
