Nice work! Looking forward to what you’ll be doing with it.

Hey, this is cool.
Have you looked into IR or Raman spectroscopy at all? This has been an interest of mine for a while-- I ended up buying a portable Raman spec off of eBay just to mess with.
I haven’t looked at anything IR - my meter is definitely not suited to it, it’s dropping off pretty hard by about 550-600nm.
But I believe this unit came out of an older Raman spectroscope lab unit. I’ve not looked into it, it’s far deeper into chemistry than I know.
I have doubts about the VM that you are referring to in the post, can you go into details, I liked the post and I am doing some tests with my spectrometer. Actually, I’m having trouble getting the spectrum in Spectrum.Studio can we talk?
It has been brought to my attention that the Science Surplus site seems to be offline.
I’ve uploaded a copy of Spectrum Studio to my site for the time being.

Hello!
I have a USB-to-USB cable…tried a USB-to-serial emulator without success…any idea?
Thanks!
What particular devices did you try to use? The spectrometer is RS232 only, so make sure you’re going to a RS232 protocol. Various other serial protocols aren’t compatible with RS232.
Thanks for posting all this info!
Your link http://www.sevarg.net/images/2023-bw-tek/SpectrumStudioSetup.zip doesn’t appear to work anymore, the Science-Surplus.com site seems to still be down, and I didn’t have any luck finding the Spectrum Studio software at the Wayback Machine.
Any chance you could post the software (and ideally the alignment instructions pdf too) somewhere I can download it from?
Thanks…

What do you mean the link doesn’t work? It seems to work just fine…

I don’t think I have the alignment instructions beyond what’s posted on my blog. You just set one parameter to 1, which gets you pixel values, and there’s a solver included that, given a bunch of pixel and wavelength relationships, solves for the rest.
It’s been a while since I’ve done it, but everything you need should be there.
Sorry - my bad. My downloads were being saved somewhere I missed them. It does work.
All I get with the software is “No Spectrometers Detected”. Is there a trick? I tried with Win10 and Win11, using a USB-to-Serial, which I know is working because I can talk to the spectrometer successfully via PuTTY (a dumb terminal).
I figured it out. Seems the software only works with FTDI chip based USB/RS-232 adapters, not ones with Prolific chips. Even tho Windows works with either. Weird.
