FIELD: instrument making.
SUBSTANCE: invention relates to a multilayer protection element and a method for its production. Multilayer body has a first layer with a first surface and a second surface opposite first surface. First surface of first layer is defined by a base plane spanned by coordinate axes x and y, wherein a large number of facet faces are moulded into second surface of first layer in a first area.
EFFECT: each of facet faces is determined by one or more of parameters F, S, H, P, Ax, Ay and Az, wherein parameters of facet faces arranged in first area are varied pseudorandomly in first area within a variation range predefined in each case for first area of surface, and wherein a reflective second layer is applied to each of facet faces.
