WebMay 2, 2012 · The microscope magnification is the product of the factors of both microscope lenses. A 40x objective and a 10x eyepiece, for example, provide a 400x magnification. Immersion Objectives: Using Oil, Glycerol, or Water to Overcome some of the Limits of Resolution WebNumerical Aperture (NA) = η • sin (α) (1) where α equals one-half of the objective's opening angle and η is the refractive index of the immersion medium used between the objective and the cover slip protecting the specimen (η = 1 for air; η = 1.51 for oil or glass). By examining Equation (1), it is apparent that the refractive index is ...
