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.

Choosing the right laser for Raman spectroscopy isn’t particularly an easy task. In the past, I initially proposed to use Thorlabs cheap CPS532 laser which has limited spectral performances that limited the spectrometer resolution to Read more…
Choosing the proper laser for Raman spectroscopy can be a difficult task. You want one that is performant enough but without having to pay the high price for it. Another difficulty adds up when recommending Read more…
Operating a laser is far from being a trivial operation. Depending on the exact temperature and current you may experience completely different behaviors! This is illustrated in Figure 1 where you can see the high-resolution Read more…
In this post I will share some of the most important tips I learned about optical systems assembly and alignment during my career. I will use OpenRAMAN as a teaching example because applying these tips Read more…
When I first started the OpenRAMAN project there is one word that resonated for me: accessibility. I wanted the project to bring Raman spectroscopy to as many people as possible, and more specifically to those Read more…
