Abstract
The present invention discloses an optical anti-counterfeiting component and an optical anti-counterfeiting product. The optical anti-counterfeiting component comprises: a substrate; a sub-wavelength surface micro-structure and an optical reflection facet formed on an upper surface of the substrate; and a multi-layer structured coating formed on the sub-wavelength surface micro-structure and the optical reflection facet. In the case where the same multi-layer structured coating is used, a contrasting optical characteristic is formed between the region in which the sub-wavelength surface micro-structure and the multi-layer structured coating lie and the region in which the optical reflection facet and the multi-layer structured coating lie, so that the optical anti-counterfeiting component or the optical anti-counterfeiting product that includes the optical anti-counterfeiting component can be identified easily and has high anti-counterfeiting capability.
