3D-printed collection channel of Raman probe designed using modular approach

This work is devoted to the development and manufacture of the collection channel for the Raman probe using 3D printing technologies. Possibilities of FFF and SLA technologies were investigated for the manufacture of optical elements holders and alignment relative to each other. The design provides for a modular approach allowing for replacing one element with another or installation additional optical elements. The Raman spectrum of aspirin was recorded by the developed probe and the results were compared with the commercial StellarNet Raman probe.
