Resolution: the ability of the lenses to distinguish fine detail and structure, that is, to distinguish between two points set at a specified distance apart. Immersion oil is used to prevent the loss of light as it passes through the slide to the objective. By preventing the loss of light, the oil enhances the resolution of the microscope.
Parfocal: when clear focus has been attained using any objective at random, revolving to another objective results in a change in the magnification but still leaves the specimen in clear focus.
Magnification: the magnification of the microscope is calculated by multiplying the magnification of the ocular by the magnification of the objective being used. Example: An ocular of 10x used with an objective of 5x gives a total magnification equal to 50x.
