The term “spectrophotometer” refers to a large category of scientific instruments used to gauge and assess how much light is absorbed or transmitted by various materials over a wide range of wavelengths. Spectrophotometers are essential tools in numerous scientific disciplines, including chemistry, biology, physics, environmental science, and materials science. These tools offer insightful information about chemicals’ characteristics, make-up, and concentration based on how they interact with light.

Spectrophotometers use spectroscopic principles to measure how much light is absorbed, transmitted, or reflected by samples. For qualitative and quantitative analysis, color measurement, molecular identification, and concentration determination produce spectrum data that can be employed. The various spectrophotometers, such as UV-visible, infrared, and fluorescence spectrophotometers, are each best suited for particular applications and wavelength ranges.

Spectrophotometers have various wavelengths that enable analysis in the ultraviolet (UV), visible, and infrared (IR) spectrums, among other parts of the electromagnetic spectrum. The spectrophotometer type and the particular application’s requirements determine the wavelength range.
