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 ...

A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to break ...

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 ...

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

Each type of light source has its own spectral distribution that show the proportions between individual wavelengths. Using spectral distributions, qualitative aspects of light such as color and color ...

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 ...

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 ...

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 ...

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 ...
