An attachment for a video screen of a cathode ray tube of a monitor or TV receiver is constituted by a glass pane having on a front side, facing away from the video screen, a multilayer anti-reflective coating. If necessary, the glass pane on a rear side, facing towards the video screen, may incorporate an absorptive coating. The anti-reflective coating is limited to two active dereflective layers. One of said two layers is a metal layer of gold or a metal alloy with a gold content of more than 50% and with a thickness of 4 to 10 nm. The second active dereflective layer is of dielectric material with a refractive power of n<1.8 and constituting an interference layer which faces away from the glass pane and which is essentially absorption-free and forms an anti-reflective layer for the visible region of the spectrum. |
