If you’re looking for noodles you’ve come to the wrong thread… 
The Raman Spectrometer Build is back in full force with new and returning expertise. Tentatively, the group will resume regularly scheduled meetings starting this Monday the 6th at 7pm in the Science Lab.
We’ll report back to this thread with progress to date and timeline goals.
I can loan the team a NIR spectrometer to use/play with if there is any interest
definitely! do you happen to know the wavelength range off hand?
900-1700 nm

@NightRanger is this the range that you need?
@careyritchey is this the only DLP optical device available presently, or are there others? Are there plans to create others with differing wavelength ranges? Is there a software interface for PC already developed? LabVIEW driver? If no, do you want one developed (LabVIEW driver, LabVIEW custom app)?
Oh and one more small question, @careyritchey, how much will these cost at low volume (10 or less at a time, also 100 at a time)? You can PM me if you like, or call 214-784-8683. I have interest aside from this project in making a interferometer for an extrememly common application.
@semaphore1999 Loaded question… but I could see us developing a professional, ready-to-use Raman system better tailored for applications for makers at DMS much faster with the loan of this NIR spectrometer… like plug-and-play faster as opposed to designing nearly every piece like we’re doing now. We’ve had offers for donations of 1064nm lasers, and the final piece of the Raman setup puzzle, a 1064 Notch Filter, is appearing within budget though this one doesn’t have the best wavelength range for our system. We can also employ other types of filters or combinations of filters in place of the notch filter though.
@careyritchey Do you have a ballpark range for time period you’d be comfortable loaning us this spectrometer? Please PM me to discuss further
I saw the tiny one the dudes were wanting to take to mass production. Not sure they are on the right path, or what?
Anyways, I integrated the LabVIEW CCD acquisition so that now it displays graph. I said I would. I did.
Here are some pics:
Thank you @semaphore1999 for whipping up this interface in LabView. I’m taking readouts and changing sensitivity settings for the detector now. I think once we zero in on why the detector is reading out different array lengths we’ll be very close to digitally acquiring a spectrum and that much closer to acquiring a Raman spectrum.
I included the array truncation feature on purpose… really I did…
But we can have a feature modification meeting tonight, since there are no bugs. lol!
