Abstract
An antireflection optical element formed from an optical material. The optical material includes a first plurality of antireflective surface structures in the form of first protuberances from the optical material. The first plurality of antireflective surface structures are constructed to aid in transmission of a first wavelength range through the optical material. Also included are a second plurality of antireflective surface structures in the form second protuberances from the first plurality of antireflective surface structures. The second plurality of antireflective surface structures are constructed to aid in transmission a second wavelength range through the optical material. The first wavelength range comprises longer wavelengths than the second wavelength range.
