  • Located in the base
57
Q

What is the role of coarse adjustment knob?

A

Allows either the stage or the nosepiece to be slowly raised or lowered to provide initial focusing

58
Q

What is the purpose of fine adjustment knob?

A

This knob moves the stage slightly to sharpen the image

59
Q

A
  • Collects and
    concentrates
    light upward
    through the
    object on the
    stage.

used to support microscope when carried and hold the entire parts

62
Q

A

support the specimen

63
Q

What is the role of nose piece?

A

Hold the entire objective lens and turn into increase magnification

64
Q

the three lenses with different
powers that magnifies the
object on the stage
1. 10 X - Low Power
Objective, yellow
(LPO)
2. 40 X – High Power
Objective, blue
(HPO)
3. 100 X – Oil
Immersion
Objective, white
(OIO)

A

Objective lenses

65
Q
  • The eyepiece
    lenses through
    which the object on
    stage is viewed.
  • Can be monocular
    or binocular.
  • Usually provide
    additional
    magnification of 5
    or 10 times.
A

Ocular lenses / Eyepiece

66
Q

What are the Proper use of Microscopes?

A

-Do not tilt the
microscope, instead,
adjust your stool so you
can comfortably use the
instrument.

-Always carry the
microscope with two
(2) hands. One hand
beneath the base and
the other hand on the
arm of the
microscope.

-Clean the
microscope lenses
with lens paper and
lens cleaner. Do not
use paper towels,
they can scratch the
lenses.

-Do not remove the
oculars or any other
parts from the body of
the microscope.

-After using the microscope,
place the LPO in line with
the ocular, lower the tube to
its lowest position, clean the
oil from the oil immersion
lens with lens paper and
lens cleaner.

-cover the
microscope after
use and return to
its proper
storage place.

67
Q

What are the hints and precautions using microscope?

A

-Forcing the fine or coarse
adjustment knobs beyond
their gentle stopping points
can render the microscope
useless.

-The lower the magnification,
the less light should be
directed upon the object.

-The fine adjustment knob
should be centered prior to use
to allow for maximum
adjustment in either direction

-If slide is inadvertently placed
upside down on the stage, low
and high power can be focused
but it will be impossible to bring
the object into focus using OIO.

-Slides should always be placed
on and removed from the stage
when the low power objective is
in place. Removing a slide when
the higher objectives are in
position may scratch the lenses.

-Those who wear
eyeglasses to correct
near-sightedness or farsightedness need not use
their eyeglasses when
focusing the microscope.

-Those who wear
eyeglasses for
astigmatism must wear
their eyeglasses when
focusing the microscope.
Microscope cannot
correct for astigmatism.

-Eyeglasses should not
touch the oculars for
proper viewing, either the
oculars or the eyeglasses
might be scratched

68
Q

Proper focusing of microscope

A

-Secure the LPO in place; make sure it is aligned with the
body tube.
-Using the coarse adjustment knob, focus the slide preparation.
-Adjust the iris diaphragm and condenser to attain light agreeable to the vision of the viewer.
-Switch to HPO; make sure it is aligned with the body tube.
-Using the fine adjustment knob focus the slide preparation.
-Adjust the iris diaphragm and condenser to attain light agreeable to
the vision of the viewer.
-Without disturbing the stage adjustment, remove the HPO in place
and drop immersion oil on the smear area.
-Switch to OIO; make sure it is aligned with the body tube.
-Using the fine adjustment knob focus the slide preparation.
-Adjust the iris diaphragm and condenser to attain light agreeable to the vision of the viewer.
