The
field
number indicates the
effective
visual
field
o{
view
for
a
particular
eyepiece, which, divided
by the
power
of the
obiective
used,
gives
the diameter of the
obiect covered
in mm
(real
f
ield).
All
eyepieces are
parfocal
within the
fine focusing range.
High
eyepoint
eyepieces
enable
easier observation,
especially
for

Combinations of Objectives and
Eyepieces
Total magnifying
power
obtained
by
the combination
is the
product
of individual
objective
power
multiplied
by individual
eyepiece
power.
A
selection
of the
combination
can
be
made
so
as to
get
the highest
resolution
of the image
(resolving
power),
the
largest
extent of object
area
(real
field) which
can be
observed without
moving the
stage
or slide,
or the
greatest
thickness of object
(depth
of
focus)
which
can
be
distinctly seen
without
raising
or
lowering
the
microscope
stage, depending
upon the
purpose
of the microscope.
Shown
below are the
results
compiled
from
the
different combinations of
obiectives and
eyep reces:
