An ultraviolet photon-counting dual-comb spectrometer. Two ultraviolet frequency combs of slightly different pulse repetition frequencies are generated at very low light levels by nonlinear frequency ...

In-line UV spectroscopy allows real-time monitoring of cleaning processes, enhancing process control and compliance with Pharma 4.0 goals. The method provides continuous detection of residual cleaning ...

Physicists achieve major leap in precision and accuracy at extremely low light levels. Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for ...

Researchers at the Max Planck Institute of Quantum Optics (MPQ) have successfully developed a new technique for deciphering the properties of light and matter that can simultaneously detect and ...

How it works: the top frequency comb is passed through a sample of interest and then into a beamsplitter. The bottom frequency comb operates at a slightly different pulse repetition frequency and is ...

Ultraviolet-visible spectroscopy (UV-Vis spectroscopy) is a cornerstone technique in many biological and chemical labs. The technique’s ability to derive useful information from the fundamental ...

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 ...
