You can try building that one. It's a DIY raman spectrometer.

Also a neat write up of a DIY near-IR spec here: https://caoyuan.scripts.mit.edu/ir_spec.html

I'm still holding out hope someone will make an open source FT-IR design. I actually need one for a project I'm working on, and I'd prefer not to shell out thousands of dollars for a used machine.

What are the key hardware differences between near IR and FT-IR? Could they be overcome with some software assisted analysis?
