Objectives

The objectives are the optical heart of the microscope. The objectives may be labeled as follows:
LD Plan-ACHROMAT 40x/0.5 Ph 1 ∞/1.0
Fig. 2 Objective (mounting position)
The total visual magnification of the stand with tube / phototube is obtained by multiplying objective
magnification by eyepiece magnification, e.g., 40 x 10 = 400x.
Numerical aperture multiplied by 1000, e.g. 0.5 x 1000 = 500x, presents the maximum useful
magnification; there is no resolution for further details above that limit.
If glass cover slips are employed, objectives can also be used with other cover glass thicknesses.
