It is one of the most important optical instruments in a laboratory. It is used for the study of spectra produced by prisms and grattings, for the measurement of the dispersive powers, wavelength of spectral lines, the refractive indices of solids and liquids etc.
It consists of three parts:
1. Collimator
2. Prism table
3. Telescope
