im·mer·sion

(i-mer'zhŭn),
1. The placing of a body under water or other liquid.
2. microscopy filling the space between the objective lens and the top of the cover glass with a fluid, such as water or oil, to reduce spheric aberration and increase effective numeric aperture by elimination of refractive effects that result from an air-glass interface; the best resolution is achieved when the space between the condenser lens and the specimen slide is also filled with the fluid.
