For decades, bulky spectrometers have been the main tools for understanding how things are made of chemicals (a thing called composition). Spectrometers are a type of lab equipment that uses prisms or ...

For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory ...

A research team has developed a broadband UV dual-comb spectrometer with which air pollutants can be continually measured and their reaction with the environment can be observed in real time. Sunlight ...

The experimental setup shown here incorporates on-chip optical parametric oscillator (OPO) technology to generate a frequency comb of laser-like light covering a wide range of frequencies with very ...

Slightly larger than a mobile phone, Ocean Optics' fiber-optic USB4000 spectrometer uses a 3648-element Toshiba linear CCD array detector and high-speed electronics. For the MARC system, the ...
