OpenRAMAN, a $3000 DIY Raman spectrometer

Raman spectroscopy is a technique in which light from a laser interacts with a sample to shift the laser wavelength. Recording the shifts with a spectrometer gives information about the sample. We’ve covered general cheap spectroscopy more than once here. OpenRAMAN is a project to assemble a Raman spectroscopy setup using about $3000 in (mostly […]
