Although the observation of optical spectra is common practice in physicsclasses, students are usually limited to a passive, qualitative observation ofnice colours. This article discusses a diffraction-based spectrometer thatallows students to take quantitative measurements of spectral bands. Studentscan build it within minutes from generic low-cost materials. The spectrometer'ssimple, didactic design allows students to fully comprehend the underlyingphysical concepts and to engage in a discussion on measurement errors anduncertainties.
