Prism spectrometer

Setup of a prism spectrometer
Setup of a prism spectrometer (low angle with light)
Setup of a prism spectrometer (high angle with light)

A prism spectrometer is an optical spectrometer which uses a dispersive prism as its dispersive element. The prism refracts light into its different colors (wavelengths). The dispersion occurs because the angle of refraction is dependent on the refractive index of the prism's material, which in turn is slightly dependent on the wavelength of light that is traveling through it.
