1. Opposed to mirrors.

   We had never suspected the existence of a silly antimirror law, and if it still exists in any hospital we trust the management will hasten to rescind it.

plural antimirrors

1. An antisymmetric operation; the operation of reflection combined with a reversal of some sort (such as color, time, size, etc); the reflection of opposites.

   The conditions are often signs of a triumphant hero's beginnings, and indeed will almost reflect, in the antimirror, Cordelia's fate.

   A physical system may be invariant under mirror operations, but also under antimirror operations, that is mirror operations combined with time reversal.

   Because of their color reversing nature, antioperations act on displacements such as p in a manner complementary to the action of ordinary symmetry operations; in the present case the antimirror acts to invert the component of p responsible for breaking the symmetry, i.e., p*, and leaves invariant the normal (expansion) component, which does not break symmetry;

2. Something that inhibits reflection; something that obscures or absorbs light instead of reflecting.

   Point is, the west wall had to have zero albedo, no reflection, the opposite of the Gymsealed floor. Actually, that's how I wanted my face to be. The Yid called it a "Light Sponge" or an "antimirror."

   The veil, in some of the poems I have discussed, functions as a kind of antimirror: a representation of the hidden side of nature.
