Parameters
Technical Terms & Concepts
Total Magnification
Total magnification of a microscope is calculated by the magnification of the objective multiplied by the
magnification of the eyepieces.
-Ex: (10x Eyepieces) x (4x Objective) = 40x Total Magnification
Field of View
Linear field of view of the eyepiece divided by the magnification of the objective
Numerical Aperture (N.A)
Calculated by n Sin
α
(max), the Numerical Aperture (N.A) is an important parameter that marks the
features of the objective and condenser’s image quality and resolution. The n” is a refractive index of the
medium
(air or immersion cedar oil) between the objective lens and the specimen. The
α
is 1/2 of the angle
between the
aperture on the objective and path of light. The larger the N.A, the higher the resolution of the
objective (and better quality of the image) is.
Object to Primary Image Distance
The distance between the object plane and the primary image plane. The conjugate distance is fixed.
Mechanical Tube Length
The distance between the objective shoulder and the ocular shoulder
