Tubes
This microscope system can be used with the tubes listed in the table below.
Attach the 10x, 15x, 20x, or 30x eyepiece to the binocular sleeve. Then, attach a camera such as a DS camera head to the
vertical tube using an adapter.
The tube is equipped with the optical path switching lever. This allows the optical path to be switched during observation using
the eyepiece and capture images using the DS camera. The distribution ratio of the light amount depends on the tube type.

* The light amount of the left eye is always 100%. The light from the optical path of the right eye is diverged to the vertical tube. (An
image in the right eye’s optical path is captured.)

P2-TERG 100/ P2-TERG 50 Trinocular Tilting Tube
This is an ergonomic tube that enables the angle of depression to
be adjusted.
The angle can be continuously changed by moving the binocular
part as indicated by the arrow in the figure.
Adjust the angle to facilitate microscopy.
The eye level can be changed also by turning the binocular part 180°.
Angle of depression: 0 to 30° (continuously variable)
For the division of the light amount with the optical path switching
lever, see the table above.
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. It 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.
