	Spectrometer is device that analyzes spectrum of incoming light beam. We illuminate a sample and analyze spectrum of the light coming out vs. the spectrum of the light coming in. The difference is absorption spectrum of the sample and from that we can deduce its chemical composition!		Spectrometer is device that analyzes spectrum of incoming light beam.
