Abstract
A light absorbing, low reflectance coating and method of fabricating the coating provided by electron beam evaporation of aluminum onto substrates bombarded with nitrogen ions to produce a randomly textured coating which traps light in a labyrinth. The coating is electrically insulating except for the first few tens of atoms which remain metallic. Absorptance exceeds 90% in the 0.4 to 16 .mu.m region. The coating is flexible and can be deposited on a polymer base.
