From: Wavelength dependence of ultraviolet light inactivation for SARS-CoV-2 omicron variants
(a) Optical setup of the wavelength-tunable UV inactivation system, (b) transmission spectrum, and (c) absorbance spectra of DMEM diluted with PBS. A laser-driven light source, which emits radiation of 170–2100 nm, was used as a broadband emission source, and the emission was selected by using a UV bandpass filter from 200 to 260 nm with a 10 nm bandwidth. We used a DMEM:PBS = 1:2 solution (blue line) because the absorbance between 200 and 260 nm is approximately the same magnitude.
