“Microscope”
“Vision is the art of seeing
things invisible”
John Ruskin
Slide 2
Compound Microscopes

Instrument fitted with objective and eyepiece
lenses and used for viewing small objects.
 Use two sets of lenses to produce magnified
image (eyepiece and objective)
 Creates two-dimensional image (length and width)
Slide 3
Parts of the Microscope
Slide 4
Eyepiece

Contains the ocular lens
 Closest to your eye
 Magnifies the image produced by the objective
lens (10x)
Slide 5
Adjustments
Coarse Adjustment: the control used to move
the objective lens or stage up and down
during initial focusing on a specimen.
 Fine Adjustment: the control used to bring
the specimen into sharp focus by moving the
objective stage up and down in very small
increments.

Slide 6
Revolving Nosepiece

The rotating device that holds the objective
lenses.
OBJECTIVES: Lens closest to specimen
High Power Objective: Lens with greater
magnification (43x, 40x)
 Low Power Objective: Lens with lower
magnification ability (10x)

Slide 7
Stage
Supports the slide being viewed
Slide 8
Transporting Microscopes
One hand on arm and one hand on
base.
Slide 9
Slides
Rest on stage or platform and are
held in place by stage clips
Slide 10
Field of View

The area visible through the microscope.
Slide 11
Total Magnification
Eyepiece x Objective Lens=Total Magnification
(10x) x (40x) = 400x
(10x) x (10x) = 100x
