Water-immersion objective,
Sp
ri nq-l oaded
The obiectives are designed
to
give
the
above
magnifying
powers
with the best
def
inition,
when
used
with a microscope
whose tube length is
'l6Omm.
Basides
the magniJying
power,
the numerical
aperture or angular
aperture
of the light cone
admitted
into the objective is
also an important
consideration,
as
it largely
determines the
resolution
or def ining
power,
depth of
focus
and the
brightness of the microscope image.
All the above obiectives
are
parfocal
within
the
fine focusing range.
For AOx objectives,
a cover
glass
(O.1
7mm
thick)
must
be used. In case the cover
glass
is unusable, use
an
NC
40x objective.
