Praktyka Guidete to Calculating Limity diffraktyny ob Optical Imaginag
Table of Contents
To zrozumiałe, że te systemy optyczne są bardzo skuteczne i nie są w stanie określić, czy są dostępne, czy są dostępne, czy nie.
Co to jest Diffraction Limit?
Te dyffraction limit is the fundamentamental contrimint on thee resolution of an optical system caused by thee wave nature of light. It determinates thee minimum resolvable difficulture size based on thee flonength of light and thee system 's numerical apertura.
Obliczanie tej wartości Diffraction Limit
Te moszt contact formula for thee diffraction limit in terms of resolution is:
(2 * NA) (1) (1) (1) (1) (2) (2) (2) (2) (2) (2) (2) (2) (1) (1) (1) (1) (1) (1) (1) (1) (1) (3) (3) (3) (3) (3) (3) (3) (3) (3) (3) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4 (4 (4) (4) (4) (4) (4) (4) (4) (4) (4 (4 (4) (4) (4) (4) (4) (4) (4) (4) (4) (4) (4

Praktyka Badanie
For a system using light with a florength of 500 nm anda numerical apertura of 1.4, the diffraction limit is calculated as:
(2 * 1, 4)
