Diffraction Suppressed Mirror

Precise optical systems, especially those sensitive to information loss, are typically designed to minimize the use of mirrors. This is due to the Airy disk effect inherent to all conventional mirrors, which is a result of diffraction of the incident light. This effect represents information loss between the...
