So i started prototyping a version of a raman spectrometer in the last couple of days. learning about different laser diodes, 3d modeliing prototyping optical setups compatible to the 3D Printable Fiber Spectrometer Kit from GaudiLabs @gaudi and learning a lot more on lenses… (which is where i am stuck at the moment). Checking this distributor from China.
Modeling those modular parts with openScad which can then be later integrated in some 3d printable setup.
At the moment i am using a module from a green laserpointer, 532nm, but i also learned that they are not suitable, as they also have the IR peak. So i am looking into a good 520nm laser diode to use, and a suitable cirtcuit for the constant current source.
Let’s organize a call for all people interested to share some ideas on how to proceed with such a low-cost / DIY raman spectrometer. Ping here to show your interest, i’ll set up a poll for choosing a date and time.
