Using Reflection Resonances to Improve Depth of Field for Imaging at Ultra-High Numerical Apertures

Not Accessible

Your library or personal account may give you access

Abstract

Imaging at ultra-high numerical apertures imposes severe constraints on the depth of field (DOF). We show how reflection resonances from underlayers can be used to enhance DOF in this regime and present an Equivalent Reflectance Approach (ERA) as a versatile design tool.
