2026 Frikkin Lasers Challenge: A 3D-Printed Raman Spectrometer

The CubeRaman is a DIY 3D-printed Raman spectrometer built by [Allegedly Science] that uses a 532-nm green laser, a dichroic mirror, bandpass and long-pass optical filters, and a microscope objective to perform Raman spectroscopy at a fraction of the cost of commercial instruments. The cube-shaped housing and kinematic mounts are mostly 3D-printed, with magnet-tipped adjustment screws for alignment. Initial tests on a raw diamond confirmed the expected Raman shift, while experiments with chemicals in glass bottles and plastic containers revealed the importance of thin-walled cuvettes and focal distance control. The builder notes room for improvement in stray light elimination and spectrometer slit width.
