Performance parameters for focusing are extended to nonparaxial conditions. These measures analyze focusing properties of systems with apodizers and superresolving masks.

Area of Science:

  • Optics and photonics
  • Electromagnetism

Background:

  • Focusing properties are crucial for understanding optical systems.
  • Current performance parameters are limited to the paraxial regime.

Purpose of the Study:

  • Extend existing focusing performance parameters to the scalar nonparaxial regime.
  • Provide a framework for analyzing complex focusing systems.

Main Methods:

  • Mathematical derivation of performance parameters in the nonparaxial domain.
  • Application of these parameters to analyze focusing systems.

Main Results:

  • Established a set of performance parameters applicable to nonparaxial focusing.
  • Demonstrated the utility of these parameters for systems with apodizers and superresolving masks.
