( 11) Rotate the diopter correction ring of the left
eyepiece to focus on the sample through this
eyepiece.
• The foregoing adjusts the diopter difference between the operator's left and right eyes,
thus enabling him to easily perform sample observation through the binocular eyepieces.
It also maintain the mechanical tube length correctly and helps high quality objectives to
fully exhibit their performance. Due also to the correct mechanical tube length, the
sample image focused with one objective is still in focus when it is observed with the rest
of the objectives mounted to the revolving nosepiece.
2. Interpupillary Distance Adjustment
View the viewfield through the binocular eyepieces.
While so doing, adjust the interpupillary distance until
the right and left viewfields coincide.
• Interpupillary distance adjustment causes the
eyepieces to rotate. However, the right eyepiece
sleeve contains a mechanism which keeps the
eyepiece in it from being rotated during
interpupillary distance adjustment.
• If the eyepiece with a built-in mask is inserted into
the left eyepiece sleeve, this eyepiece is rotated
during interpupillary distance adjustment. Therefore,
detach the rotation clamp ring from the left eyepiece
tube (See page 7), and insert the eyepiece with a
built-in mask into the left eyepiece sleeve. After
adjusting the interpupillary distance, rotate this
eyepiece to correct the angle of its built-in mask.
