Reflectance wavelength graph

WebColor measurements require a wavelength range from 380 nm to 780 nm, which is equivalent to the wavelengths that can be sensed by the human eye. Color measurements can be made by calculations based on spectral reflectance measurements by a UV-VIS spectrophotometer across this wavelength range. WebOptical properties using UV-Vis spectrophotometer shows that the transmittance of ZnO thin film is >75 and 95% in the visible region of the electromagnetic wavelength. The optical …
