Mirrors

Both LUCI instruments are going to be first-light instruments for the Large Binocular Telescope (LBT) at the bent Gregorian foci. This means, that the light is reflected three times before entering the cryostats. If we optimistically assume a reflectivity of 90 % for each mirror, we get a total efficiency of 0.729 at the bent Gregorian foci.
