Illustration Procedure
3. Optical axis setting
Put the eyepiece with scale on the eyepiece unit
and turn the diopter adjusting ring to adjust
diopter.
Project a slit as narrow as possible (length:
9mm) on the standard scale.
Judge which is wrong, the magnification unit or
eyepiece unit.
Set the magnification unit at 16× where no lens
is set. Then, check the difference of images
between when placing the slit vertically and hor-
izontally to determine that the eyepiece is cor-
rectly adjusted.
When something is wrong with the eyepiece
unit:
Use the 6SV3×5S, 3 pcs. each on left and right
sides, to move the objective lens frame (44670
1501) and adjust the difference within the stan-
dard.
After adjustment, tighten the screws well and
apply the screw lock.
When the eyepiece unit is normal:
Set the magnification unit at 40× and 25.6× and
give the same checks in
above.
See the table at left for the difference levels.
When something is wrong with the magnifica-
tion unit:
Move the image lens frames (44670 1013,
44670 1016) with each 3 pcs. of CQ2×5S at 40×
and 25.6× to be within the standard.
After adjustment, tighten the screws well and
apply the screw lock.
