OpenRAMAN is an open-source, 100% free, Raman Spectrometer designed by professional optical engineers to bring Raman spectroscopy to your lab at the lowest cost without sacrificing on performances.

We currently offer the spectrometer in a Starter Edition version designed for teaching Raman spectroscopy and a Performance Edition version which achieves a tested 12 cm-1 resolution at low costs.

All the CAD files and software source code are given under a FSF-recognized open-source license ensuring that the work benefits to the community only. No profit is generated by OpenRAMAN and all donations are reinvested in the project.
