DIY CubeRaman: A 3D-Printed, Open-Access Raman Spectrometer
A maker project called CubeRaman uses a 3D-printed housing and a 532-nm laser to build a low-cost Raman spectrometer; while the design is more accessible, it still relies on an external spectrometer and faces challenges like stray-light suppression and alignment, with early tests successfully detecting Raman shifts in a raw diamond.
