spectroscope
Wavelength separation device
A spectroscope is an instrument that separates light into its component wavelengths, producing a spectrum for analysis.
Scientists use spectroscopes to identify chemical elements by their characteristic spectral lines—each element produces a unique pattern when heated or illuminated.
The astronomer used a spectroscope to determine the star's composition.
