Study Notes
Microscope Parts and Functions
- Eyepiece (Ocular Lens): Magnifies the image, typically 10x or 15x.
- Arm: Connects the base to the head and eyepiece; used to carry the microscope.
- Stage Clips: Holds microscope slides in place.
- Coarse Adjustment Knob: Moves the stage for initial focusing.
- Fine Adjustment Knob: Refines focus after using the coarse adjustment.
- Draw Tube: Connects the eyepiece to the microscope body.
- Revolving Nosepiece: Holds and rotates objective lenses to change magnification.
- Objective Lenses: Varying magnifications (e.g., 4x, 10x, 40x, 100x). Positioned closest to the specimen.
- Stage: Flat platform to hold the slide for viewing.
- Diaphragm (Iris): Rotating disk with adjustable holes to control light intensity and cone size.
- Illuminator: Light source at the base of the microscope.
- Base: Provides support and stability for the microscope. Holds the illuminator and associated electrical components.
