<p>An optical coating, comprising porous particles, or formed from porous precursor particles. The average thickness of the coating is in the range of from 75 to 400 nm, and the surface roughness of the coating is in the range of from 2 to 300 nm. This coating provides broadband antireflective properties across the visible and near infrared part of the electromagnetic spectrum.</p> |
