Abstract:

An optical window may be configured to minimize optical aberrations. The optical window may include a laminous optical window assembly. The laminous optical window assembly may have four or more alternating layers of positive refraction material layers and negative refraction material layers. The four or more alternating layers may be configured to minimize refraction of electromagnetic rays propagating therethrough such that a given incident electromagnetic ray is substantially collinear with a corresponding transmitted electromagnetic ray.

Abstract:

An optical waveguide for guiding electromagnetic waves. One example of an optical waveguide includes a waveguide substrate, at least one layer of low index optical coating formed on a surface of the waveguide substrate, and a thin layer of metal formed on a surface of the at least one layer of the low index optical coating, where the at least one layer of low index optical coating is disposed between the waveguide substrate and the thin layer of metal. The thin layer of metal can have a thickness in a range of about 5 nm to about 20 nm. In one example, the thin layer of metal is chromium.
