A UV-NIR spectrophotometer can precisely measure transmittance and reflectance spectra over a wide range of wavelengths, from the near-infrared region to the ultraviolet region. In this example, a UV-3700 UV-VIS-NIR spectrophotometer was used to measure the transmittance spectrum of a CD substrate and the reflectance spectra of silicon wafers.
