In this study. a wavelength shifting fiber that shifts ultra-violet and blue light to green light was employed as a sensor probe of a fiber-optic Cerenkov radiation sensor. In order to characterize Cerenkov radiation generated in the developed wavelength shifting fiber and a plastic optical fiber. spectra and intensities of Cerenkov radiation were measured with a spectrometer. https://allfixelectricales.shop/product-category/rangehood-filter-material/
