These instructions will guide you through the assembly process of the foldable paper spectrometer, our low-cost introductory spectrometry kit. These instructions are an activity and you can find other spectrometry related activities in our spectrometry activity grid
Public Lab is collaborative, and we very much want YOU to post your activities to that grid too for others to see, replicate, and learn from.
If you have found any way to improve this kit, share it!

What you'll need
The Foldable Spectrometry Starter Kit comes with everything necessary to construct this, so if you bought one you can skip down to assembly; but if you'd like to build your own, you'll need:
To print this letter sized pdf; the first page has build instructions, but the second page should be printed onto sturdy black paper.
You'll also need scissors to cut out the pattern A DVD A narrow slit on plastic film -available on the public lab store here
Instructions for your spectrometer can be printed or viewed on this letter-sized PDF pattern which should also come included in your kit.
You can also follow along with these instructions:
To make a diffraction grating from a DVD-R, peel back the reflective layer, and cut a small square out of the transparent layer. See also: Preparing a DVD-R to act as a diffraction grating for more information on the optional removal of the residual aluminium and dye layers.
