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)

3. Parts of the Microscope

4. Eyepiece Contains the ocular lens Closest to your eye
Magnifies the image produced by the objective lens (10x)

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.

6. OBJECTIVES: Lens closest to specimen
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)

7. Supports the slide being viewed
Stage
Supports the slide being viewed

8. Transporting Microscopes One hand on arm and one hand on base.

9. Slides Rest on stage or platform and are held in place by stage clips
Creating a slide

10. Field of View
The area visible through the microscope.

11. Eyepiece x Objective Lens=Total Magnification
(10x) x (40x) = 400x
(10x) x (10x) = 100x
