The FFC-100 fiber-based frequency comb from Vescent Photonics is designed, when fully locked, to operate with better than 10–18 relative wavelength stability and to function as a stable wavelength calibration tool across large swaths of the near-infrared (NIR) spectrum. According to the company, factory-matched repetition rates of two or more FFC-100s enable dual-comb spectroscopy.

Advancing Near-Infrared Spectroscopy and Machine Learning for Personalized Medicine
February 12th 2025Researchers have developed a novel approach to improve the accuracy of near-infrared spectroscopy (NIRS or NIR) in quantifying highly porous, patient-specific drug formulations. By combining machine learning with advanced Raman imaging, the study enhances the precision of non-destructive pharmaceutical analysis, paving the way for better personalized medicine.
