• 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.
