Get full raman signal
Posted: Sat Apr 13, 2024 6:53 pm
Hello,
first of all i want to thanks Luc for his great work and sharing all the information and experience.
Let me short introduce my self. I am from Germany and togehter with good friend we builded the open raman spectrometer.
We are using all the parts of the performance edtion but the following parts are different(at the moment):
- Slit 20um
- BFLY-PGE-12A2M-CS camera
- 10 mW laser diode from eBay
- selfmade base plate
- modified cuvette
Now we finished the assembly and get some signal. For us it seems like the raman signal but we are not sure.
Also we are not sure if the BFLY-PGE-12A2M-CS camera is sensitive enough to catch all of the raman signal.
We decided modify the cuvette. Here the AC127-019-A is external on a cage mount so we can use the lense easily for alignment.
We also tried to put the lenses on lens tube and SM05/SM1 cage mounts, because we had trouble to fix the AC127-019-A on CP14/M without pan/tilt.
Attached a photo of the setup(yes, it looks horrible because it is still a prototype), and two images of the signals of 2-propanol/IPA and 2-propanone/acetone.
It seems we can only see the three peaks around 3000 cm-1 of 2-propanone and one peak around 3000 cm-1 of 2-propanol
We played with exposure time and gain but this is all we get. If we switch to Mono 16 we see a black/dark image only
Thanks in advance for you help
