2 MAIN UNITS AND DESCRIPTION OF CONTROLS
In
general,
selecting a smaller pinhole than the pinhole size recommended for
a
given
objective
will
not increase the axial resolution. However, in some cases the lateral
resolution may
increase.
The effect differs with the refractive index of
the
specimen and
the dispersion of
the
light
The following table shows-the recommended pinhole number for
a
given objective.
