   The zone plate's focusing ability is an extension of the Arago spot phenomenon caused by diffraction from an opaque disc. [2] A zone plate consists of a set of concentric rings, known as Fresnel zones, which alternate between being opaque and transparent. Light hitting the zone plate will diffract around the opaque zones.

9. Microchannel plate detector - Wikipedia

   en.wikipedia.org/wiki/Microchannel_plate_detector

   A microchannel plate is a slab made from resistive material (most often glass) 0.5 to 2mm thick with a regular array of tiny tubes (microchannels) leading from one face to the other. The microchannels are typically 5-20 micrometers in diameter, parallel to each other and enter the plate at a small angle to the surface (8-13° from normal ...
