Abstract: An optical structure comprising at least one stack having a central filter (1) and two sandwiching optical elements (2,3) between which the central filter (1) is interposed, wherein the central filter (1) is in a matrix material. The matrix material being doped with at least one doping agent, the central filter (1) and the two optical elements (2,3) on either side thereof being assembled by bonding layers (4a, 4b) of a material based on the same matrix material as that of the central filter, the optical elements (2,3) on either side of the central filter (1) and the bonding layers (4a, 4b) each having a refractive index equal to that of the material of the central filter or only differing from this refractive index within a range of plus or minus 0.05, preferably within a range of plus or minus 0.02.
