Spectrophotometer

Spectrophotometers are passive photometers that measure the intensity of light transmitted through a sample solution as a function of the wavelength of electromagnetic radiation. They are typically used for ground-based or shipborne observations. They can operate in the ultraviolet-to-visible (185-700 nm) or infrared (700-15000 nm) spectral ranges. They are commonly used in vegetation studies, air pollution monitoring, and water and soil quality analysis.
