Switching the Optical Path of the Tube
The trinocular tubes in this microscope system are equipped with
an optical path switching lever. To observe a sample using the
eyepiece, switch the optical path to the binocular part. To capture
images using a DS camera head, switch the optical path to the
vertical tube. Push or pull the lever to make the desired selection.
Be sure that the lever is fully pushed in or pulled out. Do not leave
the lever stopped partway.

* The light intensity of the left eye is always 100%. The light from the optical path of the right eye is diverted to the vertical tube.
(Images of the right eye’s optical path are captured.)

Adjusting the Angle of Depression (Changing the Eye Level)
When a trinocular tilting tube P-TERG100 or P-TERG50 is used,
the angle of the binocular part can be changed and adjusted to
facilitate microscopy.
The angle can be steplessly changed by moving the binocular
part as indicated by the arrow in the figure. The eye level varies
between 25 mm and 115 mm depending on the angle of the
binocular part. Additionally, turning the binocular part 180° will
raise the eye level by an extra 106 mm.
Turning the binocular part of the P-T100 Trinocular tube 180° will
raise the eye level 106 mm.
* The depression angle of the P-B Binocular Tube cannot be
changed and its binocular part cannot be turned 180°.
Adjusting the angle of depression
Notes on adjusting the angle of depression

Do not apply excessive force to the binocular part during depression angle adjustment. Doing so may cause unexpected
failure or malfunction.

When moving the binocular part, be careful not to catch your fingers in the rotary section at the bottom of the binocular part.
