From French gourp: UVEX is a spectrograph mainly intended for astronomical observations on relatively small sized telescopes. Its special property is that you can manufacture it yourself, thanks to the 3D printing technology, although if you choose to build it yourself then you must also mount and adjust from scratch. The UVEX project in its current form is therefore intended for DIYers, those who want to understand the inner workings of an optical instrument, and teachers who want to offer their students a very rich, complete and motivating educational project. Constructing and using UVEX is relevant to a number of subjects as you shift from planning to use, with the help of various physical phenomena (potentially supporting courses in physics, biology, chemistry…) and even astrophysical phenomena if the instrument is put at the end of a telescope!

I revised the UVEX program with chinese optical parts, and reproduced this spectrometer with the guidence the French group. Here is some pictures about it:
Here is also some spectra sample captured with my UVEX:
