Spectrometer

Definition

A spectrometer is an analytical instrument used to measure the properties of light across a specific portion of the electromagnetic spectrum. By separating light into its component wavelengths, spectrometers enable the analysis of materials based on their spectral signatures, making them essential tools for a variety of scientific applications, including nanofluidic analysis.
