homogeneous immersion objective
<microscopy> An objective to be immersed in a liquid of a certain refractive index and dispersion value as specified by the manufacturer of the objective. An oil-immersion objective, the most important type, is intended to be immersed in cedarwood oil (nD = 1.515) or in its manmade optical equivalent. A water-immersion objective is for dipping into an aqueous specimen mount. Alpha-monobromonaphthalene has such a high refractive index (nD = 1.66) that a very highly resolving objective (1.60 numerical aperture) was designed to be immersed in that liquid, for use by reflected light on metals and other opaque objects.
