CPC classification number: G02B27/0018 , G02B1/11
Abstract: According to the invention, a first coating and a second coating are configured so that the optical system has a colorimetric parameter of evaluation of ghost image visibility lower than a predetermined threshold, said colorimetric parameter of evaluation being based on total ghost image transmission coefficient of at least one ghost image formed by internal reflection of a light beam from a light source between at least the first surface and the second surface and by transmission through the optical system, the total ghost image transmission coefficient being integrated over a visible spectral band and depending on a spectrum of the light source.
