Optically variable interference devices

摘要

The disclosure relates to an optical variable interference device with peak suppression having a reflector (16) with first and second surfaces (17, 18). A thin film multilayer interference stack (11) is disposed on the first surface. The interference stack is comprised of at least two periods with each period being comprised of a metal absorber layer (21; 23) and a dielectric space layer (22; 24). <IMAGE>
