How a Microscope Works Ocular Lens (Magnifies Image) Objective Lens (Gathers Light, Magnifies And Focuses Image Inside Body Tube) Body Tube (Image Focuses) Bending Light: The objective (bottom) convex lens magnifies and focuses (bends) the image inside the body tube and the ocular convex (top) lens of a microscope magnifies it (again).

Body Tube• The body tube holds the objective

lenses and the ocular lens at the proper distance

Nose Piece• The Nose Piece holds the objective

lenses and can be turned to increase the magnification

Diagram

Page 8: The Microscope 6 th Grade. How a Microscope Works Convex Lenses are curved glass used to make microscopes (and glasses etc.) Convex Lenses bend light.

Objective Lenses• The Objective Lenses increase

magnification (usually from 10x to 40x)

Stage Clips• These 2 clips hold the slide/specimen in

place on the stage.

Diaphragm• The Diaphragm controls the amount of

light on the slide/specimen

Turn to let more light in or tomake dimmer.

Diagram

Light Source• Projects light upwards through the

diaphragm, the specimen and the lenses

• Some have lights, others have mirrors where you must move the mirror to reflect light

Ocular Lens/Eyepiece• Magnifies the specimen image

Arm• Used to support the microscope when

carried. Holds the body tube, nose piece and objective lenses

Diagram

Page 14: The Microscope 6 th Grade. How a Microscope Works Convex Lenses are curved glass used to make microscopes (and glasses etc.) Convex Lenses bend light.

Stage• Supports the slide/specimen

Coarse Adjustment Knob• Moves the stage up and down (quickly)

for focusing your image

Diagram

Fine Adjustment Knob• This knob moves the stage SLIGHTLY

to sharpen the image

Diagram

Page 17: The Microscope 6 th Grade. How a Microscope Works Convex Lenses are curved glass used to make microscopes (and glasses etc.) Convex Lenses bend light.

Base• Supports the microscope

Magnification

Page 19: The Microscope 6 th Grade. How a Microscope Works Convex Lenses are curved glass used to make microscopes (and glasses etc.) Convex Lenses bend light.

Magnification• To determine your magnification…you

just multiply the ocular lens by the objective lens

• Ocular 10x Objective 40x:10 x 40 = 400

Objective Lens have their magnificationwritten on them.

Ocular lenses usually magnifies by 10x

So the object is 400 times “larger”

Caring for a Microscope• Clean only with a soft cloth/tissue

• Make sure it’s on a flat surface

• Don’t bang it

• Carry it with 2 HANDS…one on the arm and the other on the base

Page 21: The Microscope 6 th Grade. How a Microscope Works Convex Lenses are curved glass used to make microscopes (and glasses etc.) Convex Lenses bend light.

Carry a Microscope Correctly

Page 22: The Microscope 6 th Grade. How a Microscope Works Convex Lenses are curved glass used to make microscopes (and glasses etc.) Convex Lenses bend light.

Using a Microscope• Start on the lowest magnification• Don’t use the coarse adjustment knob

on high magnification…you’ll break the slide!!!

• Place slide on stage and lock clips• Adjust light source (if it’s a mirror…don’t

stand in front of it!)• Use fine adjustment to focus
