Centering The Pinhole; L200Nd Epi/Dia Simultaneous Illumination - Nikon ECLIPSE L200ND / ECLIPSE L200N Instructions Manual

3.14.3 Centering the pinhole

Be sure to center the pinhole (match the centers of the pinhole and the optical path) before
observation.
Remove one eyepiece and while looking into the open sleeve, turn the pinhole centering
screws to bring the pinhole image to the center of the exit pupil of the objective. For this
adjustment, the use of centering telescope (optional) is recommended since it will facilitate
the observation of the exit pupil.

L200ND EPI/DIA simultaneous illumination

If you are using the L200ND and wish to turn on the episcopic and diascopic illumination at
the same time, use the lamp cable and the TI-PS 100W Power Supply.
After connecting the lamp cable to the diascopic lamphouse, connect the other end of the
cable to the 12VDC outlet on the TI-PS 100W Power Supply. Connect the power cord to the
power supply.
This connection shuts the power from the microscope main body to the diascopic
lamphouse. Even when the Episcopic/Diascopic Illumination selection switch (on the front)
is set to "DIA," the diascopic Illumination does not light up.
To turn ON and OFF or to adjust the brightness of the diascopic illumination, use the
switches on the TI-PS 100W Power Supply. For details on operating the TI-PS 100W Power
Supply, refer to the instruction manual supplied with the power supply.
