What is a Spectrometer? Types and Uses

What is a Spectrometer? Types and Uses

A spectrometer is a device that measures a continuous, non-discrete physical characteristic by first separating it into a spectrum of its constituent components.

Optical spectroscopy uses light to probe the properties of materials or structures. By studying the wavelength and intensity of light that is emitted, transmitted, reflected or absorbed by a material or structure, various properties of the sample can be determined.
