Mini-spectrometer From a DVD and Folded Paper

About: I am a researcher working on development of optical atomic clocks. Electronics is my hobby since childhood when my uncle was bringing me old phones to play and take apart.

Writing up experiences with an open-source transmission grating spectrometer from DVD, paper and camera. A very effective gadget to get hands-on training in spectroscopy!

Practical application: it can be used for example to check the richness of LED lamp spectra in the shops.
