Details
Shelyak Instruments is your complete echelle spectroscopy solution for your astronomical projects. It is based on our strong experience in spectroscopy (with design and manufacturing of the Lhires III and Lhires Lite) and nights of observations including with MuSiCoS & Narval spectrographs. This practical experience helped us to design a robust and productive solution in the field.
We designed the spectrograph with Christian Buil, a higly recognized optician expert. The software module has been written by Michel Pujol, an expert in Tcl/Tk and AudeLA platform. They both complement our expertise to bring you the best solution in echelle spectroscopy for astronomy!
