Designed right after the “Ecole d’Astrophysique” du CNRS (astrophysical school organized by the french national science organization) in 2003 for Be stars observation, it has since found numerous other applications.\u003c\/p\u003e\n\u003ch2\u003eResolution \u0026amp; spectral domain\u003c\/h2\u003e\n\u003cp\u003eWith a resolution power of R=17.000, it gives access to radial velocities by Doppler effect, as well as incredible details in the lines profile.\u003cbr\u003eThe standard gratings is of 2400 lines\/mm; this gives the Lhires III its full resolution. It can be quickly replaced by other optional grating modules – that makes the Lhires III a versatile instrument, it is therefore possible to adapt the actual resolution to your suit project.
