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 ...

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 ...

A multilayered semiconductor acting as an optical sensor opens the way to miniaturized, adjunct spectrometers.

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 ...

Figure 1 illustrates different operating mechanisms that enable spectral analysis. Conventionally, spectral analysis is achieved using dispersive optics such as gratings, which separate different ...

A single NMR scan using the Spinsolve™ NMR spectrometer is adequate to measure concentrations and reveal molecular structure for many samples. Figure 2 shows the spectrum of lidocaine that was ...

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 ...

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 ...

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 ...

If you have ever thought, “I wish I could have a mass spectrometer at home,” then we aren’t very surprised you are reading ...

Recently, the iGaN Laboratory led by Professor Haiding Sun at the School of Microelectronics, University of Science and Technology of China (USTC), together with the team of academician Sheng Liu from ...

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 ...
