Break apart a compact disk and…

… take a long tube, glue grating to one end, make a slit on another, profit.

I've been looking into this for about 2 months, OP.

Depends if you just want a toy, or if you actually want a piece of scientific equipment.

If the former, just follow the instructions on the Open Lab DIY spectrometer page using a DVD-R, a webcam, and some razor blades.

If the latter, it gets a lot more complicated. You'd want a linear CCD array rather than a webcam as well as a legit diffraction grating from China.

Some autist made universal software for these as well. https://hackaday.io/project/11264-universal-software-for-diy-spectrometers

Can answer probably literally any questions you have about this; dicking with spectrometers is both my day job and my hobby.

This might be a fun project for you to do.

Thanks, well it's for a uni project and my teacher showed us a picture of a black box with a prism on it and we could see the dalight spectrum on one side, it looked really simple but i dont really know where i should start

Cod no dip

1) Diffraction grating from Science First.
2) Cheap, old DSLR. I'd recommend Nikon for this, because...
Cheap, manual focus lens from the 1970s with near-zero distortion and focus at infinity
3) Any lenses, splutters, etc, you might need from Anchor Optics
4) razor blades to make the slit
5) profit

>black box with a prism on it
The good thing about prisms is you get no first-order/second-order spectrum overlap.
The bad thing about prisms is the scale is seriously nonlinear, and you get very little resolution in the blues and beyond.
E.g., OPs pic is clearly from a diffraction grating.

public lab has a 2$ DIY spectroscopy manifold.

i have a fujifilm sx1

A linear sensor array would likely give better results than a dslr (since there's no color filters you have to muck about with) and cost a couple of bucks. The resolution might also be better, depending on the model.

i have removed a bunch of those from old scanners, didn't knew if useful, thanks

>>1050862
Those have color filters though

>>1050871
Not all. Some have a light source flashing red green and blue which is then acquired by a color insensitive sensor array.
