spectrometers
Wavelength measurement devices
Spectrometers are instruments that measure properties of light or other radiation across a spectrum.
They separate electromagnetic radiation into its component wavelengths, revealing information about the composition of substances: The spectrometer detected traces of mercury in the water sample.
Different types measure mass, light absorption, or atomic emissions, making them essential tools in chemistry, astronomy, and materials science.
