A spectrophotometer, commonly known as a UV/VIS spectrophotometer, is a device used to measure radiation absorption in the visible and ultraviolet light spectrum. It is an instrument used by scientists in laboratories to investigate materials that reflect, absorb and emit light. These instruments are used in both industry and research to identify and quantify chemical compounds in a sample.
Spectrophotometers detect a range of wavelengths from ultraviolet rays to visible light. These instruments use deuterium lamps, tungsten lamps, and lasers to emit light into a sample of chemical materials or compounds, reading the resulting spectrum of transmitted light
