Background

A spectrophotometer, also called a spectrometer (spectrometer), is a scientific instrument that decomposes light with complex components into spectral lines. The measurement range generally comprises a visible light region with a wavelength range of 380-780 nm and an ultraviolet light region with a wavelength range of 200-380 nm. Different light sources have their own emission spectra, so that different illuminants can be used as the light source for the instrument. Emission spectrum of tungsten lamp: after spectral light with the wavelength of 380-780 nm emitted by a tungsten lamp light source is refracted by a prism, a continuous chromatogram consisting of red, orange, yellow, green, blue, indigo and purple can be obtained; the color spectrum can be used as a light source of a visible spectrophotometer. A dual beam spectrophotometer is a spectrophotometer that analyzes a sample by passing one of two beams of light through the sample and the other beam through a reference solution.
