Microscope Flashcards
(20 cards)
Name the different parts of the microscope
Demonstrate the correct procedure for carrying the microscope
Always carry the microscope with two hands, one on the arm and the other one on the base

How do you store a microscope
- Dust cover on
- Electric cord secured
- Light dimmed and off
- Scanning objective lens in place
- Stage dropped as low as possible
What is the function of the microscope’s Base?
Provides a heavy, stable support for the rest of the instrument
What’s the function of the Arm?
Fixes to the base, the arm provides a support for the stage and for the body tube which, in turn, supports the principle lenses
What’s the function of the Stage?
The slide is placed on this flat platform for examination
What is the function of the Mechanical Stage?
It’s the mechanism that moves to change the position of the slide. The mechanical stage rests on the stage
What is the function of the Condenser?
Lens that concentrates beam of light at the stage
What is the function of the Iris Diaphragm?
This provides the principal means by which the light intensity is changed and must be carefully adjusted for proper use
What is the function of the Rotating Nosepiece?
Objectives are mounted on the rotating nosepiece and can be rotated into position
What is the function of the Objective Lenses?
Magnify the image on the slide. There are three objective lenses; the scanning objective, the low power objective, and the high power objective
What are is the magnitude of the Objectives Lenses?
4X, 10X, and 40X
What is the Ocular and what does it do?
Is a lens that further magnifies by 10X the image produced by the image lenses
What is the “Total Magnification”?
It is obtained by multiplying the Ocular magnification(10) by the magnification of the objective in use
What is the function of the Coarse Adjustment Knob?
Is used to get the lens into approximate focus by raising or lowering the stage for clear focus
What is the function of the Fine Adjustment Knob?
It produces a a very gradual raising or lowering of the stage for a clear focus
What is the function of the Light Switch?
Plug your microscope in, turn on the light switch, and you are ready to begin
What is the Field of View?
Is the circular field that you see when you work through the microscope
What is the working distance?
Is the space between the slide and the objective lens
