Nonsense, you can run a perfectly good student lab with a cheap notch filter and pull a usable spectra off something like polystyrene or Tylenol. What I'm wonde

Nonsense, you can run a perfectly good student lab with a cheap notch filter and pull a usable spectra off something like polystyrene or Tylenol. What I'm wondering is if this thing could even do that. Looking at the abuse the diffraction grating has taken suggests the answer is no. As far as a decent scientific bench instrument goes, we're mostly in agreement. I'd love to know if you could make a decent optomechanic system like this on a SLS with a metal substrate.
