What is Spectrometer?

The spectrometer is an optical instrument used to study the spectra of different sources of light and to measure the refractive indices of materials (Fig). It consists of basically three parts. They are collimator, prism table and Telescope.

The vital purpose of a spectrometer is to capture in light, break it into its spectral apparatus, digitize the signal as a function of wavelength, and read it out and present it through a computer.
