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 ...

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 ...

Spectral (or optical) resolution is one of the most essential characteristics of a spectrometer. A system’s spectral resolution determines the maximum number of spectral peaks that can be resolved by ...

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 ...

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 ...

A research team led by Prof. Wang Zhenyou at the Aerospace Information Research Institute of the Chinese Academy of Sciences ...

We know the effect of passing white light through a prism and seeing the color spectrum that comes out of the other side. It will not be noticeable to the naked eye, but that rainbow does not fully ...

Researchers at Fraunhofer IOF in collaboration with Airbus have developed a hyperspectral spectrometer as part of the "Rainbow" project. The technology enables the creation of digital field maps that ...

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

Is there anything a smartphone can’t do these days? Apparently, they now double as spectrometers, at least when you add a special kit that’s been developed by collaborators at Public Labs. The Public ...
