1. immersion; dipping; in microscopy, immersing both the objective lens and the specimen in a liquid to increase the numerical aperture; in photolithography, filling the air gap between the final lens and the wafer surface with a liquid to increase the resolution
2. Oil immersionIn light microscopy, oil immersion is a technique used to increase the resolution 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. Typical oils used have an index of refraction around 1.515.
