The wavelength of UV radiation is crucial because different dyes and fluorophores require specific wavelengths for optimal excitation. Common UV wavelengths used in histology range from 200 to 400 nanometers, including UVA (320-400 nm), UVB (280-320 nm), and UVC (100-280 nm). Proper selection of the wavelength ensures maximum fluorescence and clear imaging of the tissue structures.
