SS-Raman spectroscopy employs a swept-source laser, a narrow-bandwidth bandpass filter (BPF), and a highly sensitive point photoreceiver for sample identification. These components enable the ...

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 ...

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 ...

A tiny polarization controlled metalens creates a flexible 3D sensor that shifts between precision and long-range modes, ...
