The lens immersion medium is the medium in which the microscope objective is immersed. Its optical activity is taken into account by the Lens Refractive Index.
Objectives are designed to work on particular immersion media, like oil, water or air. The lens immersion medium is directly related to the Numerical Aperture of the objective.
