1 Parts of the Microscope and Their Function
On the next slide there is an image of a microscope, very similar to the scopes we use in class. Click on the boxes to see the name and function of each part of the microscope.

2 Rules of using a microscope
Always carry with 2 hands Only use lens paper for cleaning Do not force knobs Always store covered Be careful of the cords

3 Parts of a microscope Contains the lens and magnifies the image for the viewer

4 Parts of a microscope Eyepiece--Contains the lens and magnifies the image for the viewer Contains the lens and magnifies the image for the viewer

5 Parts of a microscope Body tube--Tube extending from eyepiece to the objectives Tube extending from eyepiece to the objectives

6 Parts of a microscope Nosepiece--Revolving circular structure containing the objectives Revolving circular structure containing the objectives

7 Parts of a microscope Objectives Low power-4x (short) Medium power-10x
High power-40x (long) Lens that receives light from object to form a magnified image that you view through the eyepiece Lens that receives light from object to form a magnified image that you view through the eyepiece

8 Parts of a microscope Arm--Part of the microscope that is used for carrying Part of the microscope that is used for carrying

9 Parts of a microscope Stage--Surface on which the slide is placed

10 Parts of a microscope Stage clips--Used to hold the slide on the stage

11 Parts of a microscope Diaphragm--Controls the amount of light that passes up through the bottom of the stage Controls the amount of light that passes up through the bottom of the stage

12 Parts of a microscope Coarse and fine adjustment knobs
Used for focusing the microscope at different objectives Used for focusing the microscope at different objectives

13 Parts of a microscope Light source--Provides a steady stream of light that passes up through the bottom of the stage Provides a steady stream of light that passes up through the bottom of the stage

14 Parts of a microscope Base--Supports the microscope

15 Magnification Multiply the eyepiece magnification (10X) by the objective magnification (4X, 10X, 40X) Example: 4 x 10 = 40X total

16 How to use a microscope Place the slide on the stage
Use stage clips to secure slide Adjust nosepiece to lowest setting (Lowest = shortest objective) Look into eyepiece Use coarse focus knob
