From the initial sequencing of SARS-CoV-2 and the ultraviolet LEDs used in air filtration to spectroscopy-based diagnostic tests like real-time PCR, optics and photonics are enabling the fight against COVID-19.
Unlike other forms of spectroscopy whereby a reference scan decouples light-source variations from the measured spectral data, Raman spectroscopy is extremely dependent on the properties of its light source.
