e) When the right and left optical axes are
Left optical axis
Center cross hair
Fig.
11-19
compared with each other in Fig. 11-19,
for example, the right optical axis
is
nearer
the center cross hair on
KN0005. In this
case, the left optical
;xis must therefore
be adjusted within 2 divisions of the right
-
Center cross hair
.-
-
/
optical axis on thescale of KN0005 (within
the black enclosure).
(See Fig. 11 -19)
The left optical axis should (1)
edeally be
matched with the right optical axis or (2)
Right optical axis
""-
be within 2 divisions
at
the upper left
corner inside the black enclosure. Position
of the left optical axis within 2 divisions
at
the lower right corner of the black
enclosure
is
the least desirable, although
the specification is met. Adjust the left
optical axis
as
close to the center cross
hair on
KN0005 in condition (1) or (2)
described above, if possible.
f) If the right and left optical axes cannot be
adjusted within
2
divisions of the center
cross hair on
thc scale of KN0005, repeat
