Welcome to another instructable by Let’s Innovate.
In this instructable I will guide you to make your very own really cheap interferometer. Emphasis on the “really cheap” part because there are many costly kits out there you can buy but by following this tutorial you will be able to make your very own interferometer that will cost you nothing! And does not even require that much time to setup!
This project was part of my entry to the CAIE Science Project. I hope you find it interesting.
