7.12 Attaching the Tube and Eyepieces
Attach an eyepiece tube to the tube base unit and eyepieces to the binocular part of the eyepiece tube. (Tool:
2 mm hexagonal screwdriver, supplied with the microscope main body)
The basic mounting procedure is common to all eyepiece tubes and eyepieces.
1. Loosen the eyepiece tube clamp screw on
the top of the tube base unit using a hexag-
onal screwdriver.
Leave the hexagonal screwdriver inserted into
the tube clamp screw.
2. Place the eyepiece tube on the tube base
unit, and insert the round dovetail joint
(male) on the bottom of the eyepiece tube
into the round dovetail joint (female) on the
tube base unit.
3. Securely hold the tube base unit and tighten
the tube clamp screw using the hexagonal
screwdriver.
Confirm that there is no deviation or backlash
between the tube and the tube base unit.

4. Attach the eyepieces to the binocular part of
the eyepiece tube.
When inserting an eyepiece, align any one of
the three grooves on the eyepiece with the one
protrusion on the eyepiece tube sleeve.
Make sure that the right and left eyepieces
have the same magnification.
Attach rubber eye guards (optional) to the
eyepieces, if required.
