The grating spectrometer developed by us in combination with a simple C-mount camera, such as the "Rasperry Pi HQ" camera, allows you to analyse a wide variety of light sources despite the simple and inexpensive assembly. Our spectrometer achieves a resolution of approx. 1 nm in the visible wave range of 400 nm - 800 nm.
Everything you need for printing and a list of required parts as well as assembly instructions can be foundhere.
Have fun setting up and experimenting!
