2026 Frikkin Lasers Challenge: A 3D-Printed Raman Spectrometer
2 min read
Allegedly Science built the CubeRaman, a 3D-printed Raman spectrometer using a cheap 532-nm laser module. The system detected the Raman shift of a raw diamond and distinguished ethanol from polypropylene. The design is more accessible than previous open-source spectrometers but still requires a separate spectrometer.
