Attach the HNA condenser slider to the
bottom of the extension tube.
3. Insert the aperture diaphragm lever of the
HNA condenser slider into the bottom of the

Dust-proof plate of the HNA condenser
slider
The dust-proof plate is affixed to the HNA
condenser slider with two screws.
Use the screw holes on the opposite side to
mount the dust-proof plate at the reverse
position. This is useful if more work space is
required in front of the microscope.
