Up for sale is my B&W TEK 473nm RAMAN spectrometer that was initially branded as a "Pharmanex S1 Biophotonic Scanner". You get just what you see in the first picture which is a RAMAN system with laser, probe, spectrometer, fiber cables, electronics, etc, but this is not something you can just plug in and start using immediately. You are going to have to do some work to actually start using it as a complete and fully functional RAMAN setup so this would be perfect for students or DIY people for example. Luckily, there has been a forum covering these spectrometers for years including all the details anyone would ever want to know so before you purchase this item from me, I suggest you Google "B&W-tech Spectrometer & 473 module: Setup+Mods+Info" so you can read all about these spectrometers. Also, you can Google "Pharmanex S1 Biophotonic Scanner" as well. For a general video that explains what these scanners initially did, please go to "https://video.nuskin.com/cq/71944232/meet_s3_en-sd.mp4". For even more information, a paper was written about this scanner and also the S2 model which may be useful to some people. The title is "TOOLS USED IN THE DEVELOPMENT AND SUPPORT OF AN ANTI-OXIDANT BIO-PHOTONIC SCANNER" Finally, to see 2 good YouTube videos of just the DPSS laser, please go to : https://www.youtube.com/watch?v=sF2RDJISnAs and also https://www.youtube.com/watch?v=Y0KxvEvrnVE. Although the sticker on the laser says 10 watts, in actuality it is less then 1 watt. Thank you.
