=== Microscopy with Oil Immersion=== | |||
"In light microscopy, oil immersion is a technique used to increase the resolving power of a microscope. This is achieved by immersing both the objective lens and the specimen in a transparent oil of high refractive index, thereby increasing the numerical aperture of the objective lens. Immersion oils are transparent oils that have specific optical and viscosity characteristics necessary for use in microscopy."(https://en.wikipedia.org/wiki/Oil_immersion) | |||

Rays (black) coming 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."(https://en.wikipedia.org/wiki/Oil_immersion)]] | |||
