7. Eyepiece tube turret
Position of the turret Description
OEmpty
B
Bertrand
lens
The exit pupil of the objective can be observed. Turn the Bertrand
lens focusing screw to focus on the exit pupil.
If manipulator is used, this lens can also be used to observe the tip
of the manipulator located just above the objective.
C Shutter Shuts out extraneous light entering the eyepieces.
M
2.5X
magnifier
Applies 2.5x intermediate magnification only to the image seen
through the eyepieces. Useful when slight enlargement is
necessary or when performing focusing for photomicrography
using 4 to 20X objective. (Not equipped on T-TERG ergonomic
eyepiece tube.)
• There is no eyepiece tube turret on “T-TS eyepiece tube S” and “T-TI intermediate tube”.
8. System condenser
A condenser has dual functions. It condenses light, and
provides the condensed light with optical elements to enable
various types of microscopic applications
Traditional microscopes require condensers to be changed
according to microscopic applications; for example, a Ph
condenser for Ph microscopy, and a DIC condenser for DIC
microscopy.
The system condenser of this microscope features modules that
contain the optical elements. Up to five modules can be
incorporated into the unit. As a result, the user needs only to
rotate the turret in order to execute various microscopic
applications, without changing condensers.
Modules can be arranged freely in the turret if they are applicable
to the condenser lens in use (there are 2 types of condenser
lenses). Modules may be replaced without dismounting the
condenser turret unit from the microscope, enabling several
microscopic applications to be executed for a short period of
time.
• For Ph microscopy, select the module having the same Ph code as marked on the objective. Bring it into the optical path
and center the annular diaphragm. Be sure to keep the condenser aperture diaphragm fully opened or the optical path
will be obstructed by the diaphragm.
• When using the T-CT-E motorized condenser turret, be sure to refer to the instruction manual supplied with the T-HUBC
HUB controller.
