Fluorescence Visible SpectroPhotoMeter

Fluorescence visible spectrophotometers utilize the property of substances to emit fluorescence after absorbing ultraviolet or visible light. They separate specific wavelengths of light through a monochromator and detect fluorescence intensity. They are used to determine the concentration and properties of fluorescent substances in samples, such as analyzing ink composition and detecting plastic additives to determine substance content and purity.
Selection
