Trinocular Tubes
There are three types of trinocular tubes as follows:
P-TERG100 Trinocular Tilting Tube
P-TERG50 Trinocular Tilting Tube
P-T100 Trinocular tube
ttach two eyepieces of the same magnification (10x, 15x, 20x or 30x)
to the binocular sleeves of the trinocular tube in order to observe
erected images.
ttach a camera such as a DS camera to the ve
tical tube via an
adapter.
Using the optical path switching lever on the trinocular tube,
switch the optical path between sample observation using the
eyepieces and image capturing using a DS camera. The
distribution of light (%) varies depending on the tube type. (See
the table on the next page.)
On the trinocular tilting tube, moving the binocular eyepiece tube
in the direction shown in the figure changes the angle of
depression continuously between 0° to 30°. Select the optimal
angle for microscopy. The depression angle for the P-T100
Trinocular tube is 10° and cannot be changed.
Eye point variation (trinocular tilting tube with 10x eyepieces
attached):
Approx. 90 mm (25 to 115 mm from the mount joint)
Eye-point height (P-T100 Trinocular tube with 10x eyepieces
attached):
Approx. 48 mm from the mount joint
Field of view number
(Binocular eyepiece tube): 22
(Vertical tube): 18
Adjusting the depression angle
of the trinocular tilting tube
Notes on adjusting the depression angle and interpupillary distance
Do not apply excessive force to the binocular part during depression angle or interpupillary distance 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.

(Note) 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. (The image in the right eye’s optical path is captured.)
* A P-TERG100 trinocular tube or a P-TERG50 trinocular tube cannot be used together with the microscope system that
includes a C−PSN/C-PSCN Plain Stand, a C-DS Dia Illumination Stand or a C-LEDS Hybrid LED Stand.
