Description

English: Principle of immersion microscopy. Path of rays with (left half) and without (right half) immersion medium (yellow). Rays (black) comming from the object (red) at a certain angle and going through the coverslip (orange, as the slide at the bottom) can enter the objective (dark blue) only when immersion is used. Otherwise, the refraction at the coverslip – air interface causes the ray to miss the objective and its information is lost.

Deutsch: Prinzip der Mikroskopie mit Immersionsmedium. Linke Seite Strahlengang mit, rechts ohne Immersionsmedium (gelb, 4a). Lichtstrahlen (schwarz) die vom Objekt (rot) kommen, und durch das Deckglas (orange, wie der Objektträger, 2) treten, werden in einem bestimmten Winkelbereich nur dann vom Objektiv (dunkelblau, 3) aufgefangen, wenn durch Immersionsmedium eine Brechung am Übergang vom Deckglas zur Luft verhindert oder zumindest verringert wird.
