Yeah one thing I am interested in doing is pulling together all the variables and make a calculator to get simulated results based on all your factors I listed before in that email. Right now, for example, there's not a way to easily know how much laser power you need to tell your limit of detection...

I've lost a little bit of enthusiasm for this. In my experimentation it turns out Luc's choices mattered more then I thought. You need a pretty sensitive and high resolution spectrometer. You need a narrowwidth laser, and the lenses have to be aligned just right to capture the light. Without these i...

I think you wrote FMJ on the website, I figured it was a language translation thing

Laser sintering, sls stands for "Selective Laser Sintering "

FMJ -> Multi jet fusion

PA 12 should be fine to my knowledge

You might try dyed black for the finishing

Hope this helps

Okay, that makes sense, thank you!

This is hurting my brain a little bit. I think in my head the slit was projected directly onto the sensor but that doesn't make sense because for a 30um slit and 400nm range this would be a 12,000um big. The detector is 3.45um * 2048 so 7066um. So that doesn't make any sense. Okay so thinking of is ...

Based on my measurements, it appears to be 0.4 - 0.8nm based on the smallest two peaks that I saw resolved for the performance edition (30um slit). I found a theoretical equation online that looks like lambda = ((resolution factor) * (spectral range) * (slit width)) / (number of pixels * width of pi...

I've had the same issue though before but it worked for me after
I keep trying

That might be tough based on my understanding, In Raman spectroscopy [1] McCreery notes that the how much raman signal you get back per molecule seems to be less in gas phase vs liquid by about a third (page 25). Given it's already .1% as dense you are looking at .03% concentration or 300ppm. I thin...

Here's my guesses at answers though it might be wrong: You don't want stray light, black helps absorb it. Inside the cuvette holder there is a mini beam dump structure. Whatever material you use try to avoid one that glows (floresces) PLA is more brittle and less precise. I think there are some phot...
