[0002] Spectrophotometer, also known as spectrometer, is a scientific instrument that decomposes complex light into spectral lines. The measurement range generally includes the visible light region with a wavelength range of 380-780nm and the ultraviolet light region with a wavelength range of 200-380nm. Different light sources have their own unique emission spectra, so different illuminants can be used as the light source of the instrument. The emission spectrum of tungsten lamp: The spectral light with a wavelength of 380-780nm emitted by the tungsten lamp light source is refracted through a prism to obtain a continuous color spectrum composed of red, orange, yellow, green, blue, indigo, and purple; this color spectrum can be used as the light source of the visible light spectrophotometer.
