Hi Luc,

I don't have urea with me now. I tried using styrofoam but no Raman spectrum was captured. Could it be the styrofoam was too fluffy? I used polyethene crystals. Is it important to use powder or crystals?

Also, if I want to improve the alignment, what would you suggest I adjust?

Hi Luc, Thank you for your reply. I tried some more times and managed to find the Raman spectrum. :D I'll be looking to try to improve the quality of the spectrum (it's weak and quite noisy). I have attached the Raman spectrum of a polyethene sample below (I am using the solid cuvette version). Coul...

Hi Luc, Thank you for your advice, I went ahead with the camera and it just got delivered. But even though I could capture the spectrum of fluorescent lamp, I could not capture any Raman spectrum. It's quite strange because with a phone camera placed in front of the diffraction grating, pointing tow...

Hi all, I'm am currently selecting a camera and camera lens for my Raman spectroscopy setup. About the camera lens, would a longer focal length or shorter focal length be better? For the camera, I am quite low on budget so I'm planning to buy from Taobao... The specific model I am looking at is JHEM...
