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.
Claims23
An optical window configured to minimize optical aberrations, the optical window comprising:
- a laminous optical window assembly having four or more alternating layers of positive refraction material layers and negative refraction material layers, the four or more alternating layers 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.
A system comprising:
- an optical device configured to receive and/or transmit electromagnetic energy;
- and
- an optical window configured to house the optical device and to minimize refraction of electromagnetic energy propagating therethrough such that a given incident electromagnetic ray is substantially collinear with a corresponding transmitted electromagnetic ray that is received by the optical device.
