2.5 Objectives
The objectives are the optical heart of the microscope. The objectives may be labeled as follows:
Plan-ACHROMAT

×
/0.25

Phase contrast objective with green
inscription and phase stop Ph 2
Objective magnification multiplied by eyepiece magnification results in overall visual magnification, e.g.
10 x 10 = 100x.
Numerical aperture multiplied by 1000, e.g. 0.25
×
1000 = 250

, presents the maximum useful
magnification; there is no resolution for further details above that limit.
When immersion objectives are used, the air between the cover slip and the objective is replaced by a
liquid, which in most cases is immersion oil. The plastic oiler containing 5 ml of immersion oil is
particularly suitable for this purpose.
Because of their short working distances, the 40
×
, 40x/Ph 2 and 100x/Oil objectives are equipped with
resilient mounts for specimen protection.
