Researchers at the US National Institute of Standards and Technology (NIST) and collaborators have demonstrated a compact frequency-comb apparatus that rapidly measures the entire infrared band of ...

An infrared frequency comb small enough to fit on top of a table has been used to probe the structure and composition of a complex protein molecule. Scott Diddams at the National Institute of ...

Electromagnetic waves have a characteristic frequency and wavelength that are inversely proportional; as one increases, the other decreases. Measured in Hertz (Hz), human eyes can perceive light ...

Scientists have developed a frequency comb light source in the mid-IR wavelength band. These frequency comb light sources with an extended spectrum can be used for real-time, extremely high ...

Chemical compounds all carry distinctive absorption "fingerprints" within the mid-infrared spectral region of 2 to 12 microns. This offers an opportunity to measure and study chemicals at ...
