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.
