Using the Eyepiece Micrometer Disk
(Figs. 15)
}When the WHN10X-H (or WHN10X) eyepieces are used, an eyepiece
micrometer disk can be inserted in one of them. When the eyepiece
does not have a diopter adjustment mechanism, however, it is hard to
focus on the micrometer disk if the operator has poor eyesight. Should
that be the case, adjust the focus with eyeglasses on.
Use an eyepiece micrometer disk with a diameter of 24 mm and thick-
ness of 1.5 mm.
Following Fig. 15
-1
, turn the built-in micrometer-mounting frame ² coun-
terclockwise to remove it from the eyepiece and place a micrometer disk
@ into the mounting frame. The engraving on the eyepiece micrometer
disk should face downward in the micrometer-mounting frame.
Screw the micrometer-mounting frame back into the eyepiece.
}When the WHB10X-H (or WHB10X) eyepieces are used, an eyepiece
micrometer disk with a diameter of 20.4 mm and thickness of 1 mm can
be inserted in one of them using the 20.4RH reticle holders ³ (2-piece
set). When the eyepiece does not have a diopter adjustment mecha-
nism, however, it is hard to focus on the micrometer disk if the operator
has poor eyesight. Should that be the case, adjust the focus with eye-
glasses on.
When the reticle holders are used, the field number becomes 19.6.
The field number of the U-CTBI's built-in eyepieces is 18, so it does not
change.
1. Remove both eyepieces. (When the U-CTBI is used, remove only the
right eyepiece by unscrewing the clamping screw on it with a precision
flat-blade screwdriver.)
2. Place an eyepiece micrometer disk | in one of the reticle holders ³ so
that the engraving on the eyepiece micrometer disk faces downward.
3. Screw the reticle holder ³ containing the eyepiece micrometer disk |
into the bottom of the eyepiece.
At the end of screwing, turn the reticle holder by hooking your nail on its
notch
5
to screw it all the way in.
4. To provide the other eyepiece with the same field number, screw in the
other reticle holder, without eyepiece micrometer disk, into the bottom of
the other eyepiece.
5. Replace the eyepiece(s) in its(their) original position(s).
