Terms describing the optical features of microscope
Total Magnification : Total magnification of a microscope is the individual magnifying power of the objective multiplied by that of the eyepieces.

Numerical Aperture (N.A) : One of the important factors determining the efficiency of condenser and objectives. it is represented by the formula. ( N.A. = n sin a )

Where n is the retractive index of a medium and ‘a’ is half of the maximum angle at which the light rays enter or leave the lens from or to a focussecd object point on the optical axis.

Working Distance : Clearance between the from of the objective and the upper surface of the cover glass when the image of a specimen is brought into sharp focus. Generally, the higher the magnifying power of the objective, the shorter the working distance.

Field Diameter : Diameter (MM) of the field of view which can be observed through the eyepiece. Indication 10x on the top of the eyepiece shows that eyepiece magnification is 10x.
