Assembling and operating
5-2-1
Assemble phase-contrast slider
(See fig.29)
1. Place phase-contrast slider
①
upward (on letters
side), insert it into the illumination holder from the
right to the left.
2. Each diaphragm has its corresponding part. Enter
the diaphragm into optical way by shifting the
phase-contrast until hearing a click.
3. Keep the adjusting ring of aperture diaphragm in
“
○
” when do the phase-contrast observation.
5-2-2
Center the light loop
(See fig.30&31)
★
XDSLP needs no centering
1. Place specimen on the stage, and focusing.
2. Remove the eyepiece, and replace it with CT
(centering telescope), insert in to the tube without
diopter adjustment.
3. Make sure the matched phase loop (in the
phase-contrast objective) and the light loop (in the
phase-contrast slider) is shifting into the optical
way.
4. While observe into the centering telescope, turn the
fine focusing knob which corresponding to the
light loop
①
to focus the phase loop
②
of the
objective.(See fig. 30)
5. Insert the phase center adjusting rod
④
into two
holes
③
on the phase-contrast slider, then
adjusting them until the light loop
①
center
overlay with phase loop
②
center. (See fig.30 &
fig.31)
6. Repeat the steps to center the other phase-contrast.
Remember to use the same phase-contrast slider
with 10X and 20X. Shift the optical way into the
objective which is not centered to see if the light
loop
①
is away from the phase loop
②
. Repeat the
centering steps if it is away. (See fig.30)
