Set the microscope for the bright-field microscopy under the diascopic illumination.
When the "Other items required" (See the column at the right edge of Table 2.1.) is used for the episcopic
illumination, remove each attachment from the optical path in advance.

1 Push in the optical path changeover lever for the
eyepiece tube and select 100% for the binocular
eyepiece. (See 3.4.1.)
2 Push in the BD field changeover lever to select the
"BF (bright-field)" position. (See 3.3.)
3 Turn the revolving nosepiece to place the 10X
objective into the optical path. (See 3.9.2.)
4 Place the NCB filter on the supporting pillar for
dia-Illuminator into the optical path and
compensate the color temperature. (See 3.23.5.)
5 Adjust the brightness of the diascopic illumination
roughly with the light intensity control dial for the
TI-PS100W power supply and the desired ND filter
on the pillar illuminator. (See 3.23.1 and 3.23.5.)
6 Turn the field diaphragm dial for the supporting
pillar for dia-Illuminator clockwise to the limit and
fully open the field diaphragm for the diascopic
illumination. (See 3.23.3.)
7 Turn the aperture diaphragm lever for the system
condenser clockwise to the limit and fully open the
field diaphragm. (See 3.23.4)
8 Turn the condenser focus knobs for the supporting
pillar for dia-Illuminator and lower the condenser
mount to the limit. (See 3.23.6.)
• When the ELWD condenser lens is attached to
the system condenser, lower the condenser
mount approximately 1 cm from the upper limit.
• When the ELWD-S condenser is used, lower
the condenser mount approximately 2 cm from
the upper limit.
9 Turn the turret of the condenser to the "A" position
to place the bright-field condenser cassette into
the optical path.
