5-5 Technical terms
(1) Total magnification=(magnification of objective) X (magnification
of eyepiece)
(2) Field of view=(line field of view of the eyepiece selected)
÷(magnification of the objective selected)
(3) N.A.=n·sinα (max), N.A.is very important parameter which marks
the features of the objective and condenser. The “n” is the refractive
index of the medium (air or immersion oil) between the cover glass
of the objective and the specimen. The
“α” is the half of the aperture
angle. The N.A.is bigger, the resolution of the objective is higher.
(4) Object to primary image distance: the distance between the object
plane to the primary image plane. The conjugate distance is fixed.
(5) Mechanical tube length: The distance between the objective shoulder
and the ocular shoulder.
