T-Dh Dia-Illuminator 100W - Nikon ECLIPSE TE2000-E Instructions Manual

• The fine focus knob is disabled at the Escape position.
• If the objective is at the Escape position, turning the coarse focus knob to move the objective position more than 0.5 mm
will clear the memorized position.
• Pressing the REFOCUS switch and ESCAPE at the same time will clear the memorized position.
• If the T-ND6-E sextuple motorized DIC nosepiece and the T-RCP remote control pad are also in use, automatic
Escape/Refocus movements can be set to correspond to objective switching. For detailed information, see the
instruction manual for the T-RCP remote control pad.
• The coarse focus knob turns during Escape/Refocus movements. To prevent malfunctions, avoid contact with the
coarse focus knob while these movements occur.
• Turning the coarse focus knob will turn the motor set inside. On rare occasions, you may find that the coarse
focus knob fails to turn smoothly. This is because it engages the gear inside the motor. To restore smooth
movement, slightly turn the coarse focus knob in the opposite direction, then turn once again in the original
direction.

Condenser refocusing clamp
After focusing the field diaphragm image on the specimen surface
using the condenser focus knob, turn the condenser refocusing
clamp clockwise to mark that position.
Even if the condenser is raised for specimen replacement, it can be
easily returned to the field diaphragm image in-focus position by
only lowering it to the limit. It is very useful when high N.A.
condenser lens is used or when the dia-illuminator cannot be tilted
for specimen replacement. The condenser refocusing clamp
works in range of 13 mm.
Rotating the condenser mount
To rotate the condenser mount, loosen the condenser mount
rotation clamp screw.
This function is mainly used for adjusting the vibration direction on
DIC microscopy.
When the system condenser is used and the polarizer is not
attached (such as when performing bright-field or Ph microscopy),
this function can be used to shift the condenser turret to the left or
right to make space for the manipulator or the other system.
(can be used only when LWD condenser lens is attached)
