Thanks! That's a great question, the reason we added the shutter was to turn the laser off during time-lapse acquisitions of colonies. The Chlamydomonas are sensitive to light and keeping the laser on them for longer can increase their stress and effect their phenotypes. Rather than figuring out how ...

We just released our pub "AutoOpenRaman: Low-cost, automated Raman spectroscopy"

Our goal was to create something relatively inexpensive that allows us to collect Raman spectra from hundreds of algae samples automatically. Our modifications include a motorized XY stage, a Z stage, a built in neon ...

Hi Luc, thanks again for your response, I hope you are recovering well!
I've attached one of the better spectra of salicylic acid we have been able to get, this is with baseline removal off, exposure set at 1122ms, gain set at 28, and num avg set at 10.
How critical would you say tuning the ...

Hi Luc, thanks for your response, I have just a few clarifying questions.
1) What is the axis/direction for the green curve? If the green curve is the sum of the rows and we want the bell shape in the center where our ROI is, wouldn't we expect the bell to be curved in the other direction? I guess ...

Hi, just wondering if anyone has resources/an explanation of how the saturation feature on the SpectrumAnalyzer software works? We have been getting good raman signal of salicylic acid (yay!) with our solid cuvette attachment and want to further improve our signal to noise.
I've watched the ...

We have released the pub from our hackathon which used the OpenRaman to collect spectra of beer, chilis, and algae!
Raman spectroscopy enables rapid and inexpensive exploration of biology

I helped build a starter edition for our labs Raman hackathon!
Our first attempt has an FDM printed base plate we tried while waiting for the aluminum base plate.

The second attempt has the aluminum base plate which was much more stable. We used a FDM printed camera mount ...
