Optical spectrum is a set of wavelengths which is created by a light source. Radiation of each element or composition can be absorptive or reflective and unique. For measurement of these spectra, an apparatus known as spectrometer can be used. In reality, spectrophotometer is a machine which measures the intensity of the absorbed light as a function of wavelength. Owing to the extensiveness of the radiational energy amplitude, various spectrophotometers are used for different purposes. The main purpose of this research is to use spectrophotometer and design of a spectrometer for diagnosis and evaluation of icterus in children and measurement of blood sugar in people suffering from diabetes. Statistical population of research includes 80 newborns suffering from icterus and 160 diabetic people in Al-Zahra hospital which are selected randomly. In this method, all of the samples are evaluated with regard to the absorbed light. Results imply to the 78% accuracy for diabetes and 84% accuracy in newborns.
