Study Notes
Parts of a Compound Microscope
-
Eyepiece or Ocular Lens
Magnifies the specimen usually by 10x; the lens you look through. -
Coarse Adjustment Knob
Moves the stage up or down to bring the specimen into focus; the first knob to be used for focusing. -
Fine Adjustment Knob
Sharpen images under low and medium power; essential for high power focusing. -
Revolving Nosepiece
Mounts the objective lenses; allows selection between low, medium, or high power lenses by rotation. -
Objective Lenses
Three lenses for magnification: Low (4x), Medium (10x), and High (40x). -
Stage
The flat platform where slides are placed for observation; should be kept dry. -
Stage Clips
Secure slides in position on the stage to prevent movement during observation. -
Diaphragm
Contains holes of varying sizes to control the amount of light passing through the specimen. -
Lamp
Provides light necessary for viewing specimens; microscopes without a lamp may use mirrors to reflect natural light. -
Arm
Holds the microscope's tube in place and serves as the handle for carrying the microscope. -
Base
Offers a stable support for the entire microscope structure. -
Tube
Separates the ocular lens from the objective lenses, ensuring proper distance for effective magnification. -
Condenser Lenses
Located beneath the stage, these lenses help concentrate light onto the specimen for better visibility.
