Elevating The Condenser; Adjusting The Position Of The Condenser (Centering) - Nikon ECLIPSE Ti2-U Instruction Manual

Chapter 3 Usage of Components
3.4.2

Elevating the Condenser

Turn the condenser focus knob to vertically move the condenser so that the field diaphragm image can be
seen clearly in the field. The movement of the condenser can also be limited so that it does not go below the
designated position.
 Operation:
Elevating movement of the condenser
Condenser focus knob
Turn it to the rear side.
Turn it to the front side.
Restriction on the lower limit position of the
condenser
Condenser refocusing
clamp
Tighten it.
Loosen it.
Adjusting the rotational torque of the condenser focus knob
The rotational torque of the condenser focus knobs on both sides can be adjusted by turning them in the
opposite direction. Turn and tighten the handles to increase the rotational torque and turn and loosen the
handles to decrease the torque.
Take care not to decrease the torque too much, as that will cause the condenser to slide down by its own
weight.
Using the condenser refocusing clamp
Even when the condenser is moved upward to the escape position to replace samples, the condenser can
be returned to the original position by lowering to the limit position. Use this clamp when using a high NA
condenser or when the dia-illumination pillar cannot be tilted.
3.4.3

Adjusting the Position of the Condenser (Centering)

Adjust the position of the condenser so that the illumination is at the center of the field. Turn the two
condenser centering screws on the front surface of the condenser mount to adjust the position using a 2 mm
hexagonal screwdriver.
 Operation:
Condenser centering
screw
Turn it clockwise
(tighten).
Turn it counterclockwise
(loosen).
Adjusting the position of the condenser
• Place the 10x objective in the optical path and stop down the field diaphragm so that the field
diaphragm image aligns with the center of the field.
• To adjust the position precisely, place a high-magnification objective in the optical path and perform the
centering in the same way.
