underneath the specimen stage.
3. If you are unable to adjust the mirrors enough to properly illuminate the specimen, you can also
tilt the stand column (10) backwards to change the position of the mirror.
Viewing a Specimen
To view a specimen:
2. Press downward on the back portion of the spring-loaded specimen holder clips (8) to raise the
front of the clips off of the specimen stage (5).
3. Place a specimen slide under the specimen holder clips (8) and center the specimen directly
over the hole in the center of the specimen stage (5).
Your are know ready to focus and view the specimen, but first you must take some precautions so
as not to damage the specimen slide or objective lens. Your microscope is equipped with a focus
travel safety screw (9) which allows you to regulate the range travel on the focuser. This assures
that the objective lenses will not accidentally come in contact with specimen slide, breaking the slide
or scratching the objective lens. To adjust the travel on the focuser mechanism:
7. Raise the objective lens away from the specimen stage (5) by rotating the course focuser knob
(12) backwards.
8. Unthread the focus travel safety screw (9) about two-thirds of the way.
9. Turn the objective lens rotator (3) until the 40x lens is over the specimen.
10. Lower the objective lens over the slide until the tip of the lens is slightly above the specimen
slide. (Be careful not to touch the objective lens to the slide).
11. Thread the focus travel safely screw (9) upward until it stops against the focuser mechanism.
12. Rotate the knurled locking nut upward to lock the safety screw in place.
Focusing:
Now that the specimen slide is placed directly under the objective lens, use the course focus knob
(12) to focus on the specimen.
Always start with the lowest power (4x objective lens and 10x eyepiece) and switch to higher
power by rotating the objective lens rotator (3). Be cautious not to let the objective lens touch
the specimen slide when changing to higher power.
Use the fine focus knob (11) to change the depth of field on the specimen you are observing.
If you run out of downward travel before reaching sharp focus, you can unscrew the focus travel
safety screw (9) to allow for more downward travel. Once again be careful not to let the
objective lens touch the specimen slide.
