DIY Spectrometer

Simply DIY spectrometer built using a regular webcamera.

I built this as I needed to get the spectral data of the reflectivity for some pigments I'm developing but didn't find any designs of these DIY spectrometers that was setup to do that. This design is setup to be modular and easily configurable.


===============================================================

Besides the printed parts it needs

1 webcamera you can take apart
I'd link the one I used but the listing no longer shows the same camera but most any should work fine

1 M3 bolt (10-20mm long) and nut to mount the camera bracket

1 diffraction grating slide, I used the 1000 lines/mm and that works fine

4+ 5mm white LEDs (or your preferred light source for your use)
I initially just used 4 but then designed a housing that could fit 12 but never used it.

your preferred adhesive to mount the camera (I used hot glue)

Some black tape (I used gaffers tape)
This is to seal up any ope
