2 ESO B

The Microscope

Page 2: Parts of a Microscope - Ciencias SEK-Atlántico...compound microscope, as they are the lenses closest to the specimen. *A standard microscope has three, four, or five objective lenses

What do we use the

microscope for?*It's used to look at microscopic

particles, those which are not visible to the naked eye.

*It is used by scientists for the study of tissues and cells.

*It is also used in examining forensic evidence obtained from a crime scene

*To study the health of a particular ecosystem.

*It helps in the study of atomic structures.

History

*The first scientist who used the microscope was

Galileo in 1610.

*Between 1660-1665, Marcello Malpighi began to study

the living matter.

*Antony Van Leenwenhoek called “Father of Microscopy”

improved the microscope and saw bacterias, yeast,

blood cells and protozoos.

Page 5: Parts of a Microscope - Ciencias SEK-Atlántico...compound microscope, as they are the lenses closest to the specimen. *A standard microscope has three, four, or five objective lenses

Eyepiece: Are the lens that the viewer looks through to see the specimen. The eyepiece usually contains a 10X or 15X power lens.

Diopter Adjustment: Useful as a means to change focus on one eyepiece so as to correct for any difference in vision between your two eyes.

Page 6: Parts of a Microscope - Ciencias SEK-Atlántico...compound microscope, as they are the lenses closest to the specimen. *A standard microscope has three, four, or five objective lenses

*Body tube (Head): The body tube connects the eyepiece to

the objective lenses.

Page 7: Parts of a Microscope - Ciencias SEK-Atlántico...compound microscope, as they are the lenses closest to the specimen. *A standard microscope has three, four, or five objective lenses

*Arm: The arm connects the body tube to the base of the

microscope.

Page 8: Parts of a Microscope - Ciencias SEK-Atlántico...compound microscope, as they are the lenses closest to the specimen. *A standard microscope has three, four, or five objective lenses

*Nosepiece: The viewer spins the nosepiece to select different

objective lenses.

*Objective lenses: One of the most important parts of a

compound microscope, as they are the lenses closest to the

specimen.

*A standard microscope has three, four, or five objective lenses

that range in power from 4X, 10X, 40X and 100X.

*Stage: The flat platform where the slide is placed.

*Stage clips: Metal clips that hold the slide in place.

Page 10: Parts of a Microscope - Ciencias SEK-Atlántico...compound microscope, as they are the lenses closest to the specimen. *A standard microscope has three, four, or five objective lenses

Stage height adjustment (Stage Control): These

knobs move the stage left and right or up and down.

Page 11: Parts of a Microscope - Ciencias SEK-Atlántico...compound microscope, as they are the lenses closest to the specimen. *A standard microscope has three, four, or five objective lenses

Coarse adjustment: Brings the specimen into general focus.

Fine adjustment: Fine tunes the focus and increases the

detail of the specimen.

Page 12: Parts of a Microscope - Ciencias SEK-Atlántico...compound microscope, as they are the lenses closest to the specimen. *A standard microscope has three, four, or five objective lenses

Illumination: The light source for a microscope. Most microscopes now use a

low-voltage bulb.

Iris diaphragm: Adjusts the amount of light that reaches the specimen.

Condenser: Gathers and focuses light from the illuminator into the specimen

being viewed.

What can we see with the

microscope?

We can observe differents cells,

microorganisms and another things like

tissues, hair, synthetic fibres, parts of

vegetables, etc.
