K5X and WFlOX incorporate a sliding
eye
shield.
This shield can be
pulled
our to prevent glare
and
loss
of contrast caused
by
ambient tight hitting the

The

N.A.
(Numerical aprture):
The numerical
aperture
represents
a
performance
number
which could
be compared
to
the relative aperture (f-number) of
a
camera lens.
M.A. values can
t~
used for dimtly
comparing the m l v i n g
powers of all
types
of objectives. The
larger
N.A, the
higher
the
resolving power.

by
its ability
to separate two
