Choice of objectives
The objectives are the centerpiece of the microscope. The following is an example of how objectives can
be labeled:
CP-"Achromat" 10
/0.25
/-
where
10
=
objective magnification
0.25
=
numerical aperture
=
infinite tube length
-
=
usable for covered and uncovered specimens
or
0.17
=
only for covered specimens with a cover slip thickness of 0.17 mm
The objective magnification multiplied with the eyepiece magnification (minimum 10x) results in the
visual overall magnification: e.g. 10
10 = 100
.
The numerical aperture
1000, e.g. 0.25
1000 = 250, is the highest useful magnification, i.e. no
further details are resolved above that limit.
The "
"sign means that these objectives cannot be used with microscopes the objectives of
which are labeled with "160" for the mechanical tube length.
