Adjusting the interpupillary distance

Using the pre-focusing lever

The pre-focusing lever prevents the specimen from being damaged by

collision between the specimen and objective.

After bringing the specimen into focus with the high magnification

objective, rotate the pre-focusing lever a in the arrow direction until

it stops.

To provide a certain margin for focusing range, rotate the pre-focusing

lever a by about half turn in the direction opposite to the arrow

direction from the stopped position.

NOTE

TIP

The interpupillary distance adjustment is to adjust the distance between

two eyepieces according to the distance between your eyes. This makes

it possible to observe a single image and to reduce eye strain during

observation.

Keep the right and left eyepieces horizontally. While looking through

the eyepieces, move the binocular portion either in a or b direction

until the right and left fields of view coincide completely. The value

shown by the indicator (protrusion) c on the left side eyepiece sleeve

represents your interpupillary distance.

TIP

If the pre-focusing lever is not positioned appropriately,

the stage may not rise and the specimen may not be

focused. In this case, adjust the pre-focusing lever

position again.

It is recommended to use the pre-focusing lever to prevent the

specimen from damage, but if you do not use the pre-focusing

lever, rotate the pre-focusing lever in the direction opposite to

the arrow direction until it stops.

· Note your interpupillary distance so that it can be easily

adjusted next time.

· You can adjust your interpupillary distance by moving the

binocular portion either to upper or lower side. Select the upper

side or the lower side according to your observation posture.
