Raman spectroscopy is a very powerful analytical technique that can be used for the identification of almost any sample .Unfortunately , commercial raman spectrometers are quite expensive so i have decided to make a "cheap" and fully functional raman spectrometer

I couldn't help notice a lack of written material, esp a numeral-labeled diagram. Hoping this is an oversight or work-in-progress bcuz it has my interest tweaked. 'More maps, pictures & graphs' to keep my interest please. A lead on component acquisition & prices would be most appreciated too. Dichroic beam splitter & mirror sizes, microscope occular power. Get back with me ASAP. I like what I see

Hi and sorry for the slow reply, yeah you are right, indeed I've a more detailed document related with the specifications and performance of my spectrometer, however it's not in English.. At the moment I don't have enough time to complete it and translate but I'll try to do it in a couple of months. In the meantime. If you have any other general question regarding the spectrometer and its results, I will be glad to answer you!

What are the specifics on laser power? What do you use for the infrared blocker? What power microscope lenses do you use at #8 & 17?

Thank you
