Study Notes
Microscope Parts & Functions
-
Ocular Lens (Eyepiece): Contains a 10x magnifying lens; monocular has one, binocular has two ocular lenses.
-
Eyepiece Tube: Connects the ocular lens to the objective lens.
-
Objective Lenses: Magnify specimens with varying power; options include 4x (low), 10x (medium), 40x (high), and 100x (highest).
-
Revolving Nosepiece: Holds and allows rotation of objective lenses into position above the specimen.
-
Arm: Structural support connecting the base to the eyepiece tube and nosepiece; used for carrying the microscope.
-
Central Aperture: Opening in the stage permitting light to pass through to the specimen.
-
Stage: Flat platform where specimen slides are placed for observation.
-
Mechanical Stage Knobs: Allow lateral and vertical movement of the specimen slide.
-
Coarse Focus Knobs: Adjusts the position of the eyepiece tube or stage for initial focus, specifically with the 4x objective lens.
-
Fine Focus Knobs: Provides precise focusing control for higher objective lenses (10x, 40x, 100x).
-
Substage Condenser: Gathers and focuses light from the illuminator onto the specimen.
-
Condenser Knob: Adjusts the position of the condenser to regulate lighting on the specimen.
-
Iris Diaphragm: Controls light intensity reaching the specimen.
-
Filter (Blue): Improves the quality of light emitted from the light source.
-
Filter Holder: Secures the optical filter in position.
-
Light Source (Illuminator): Illuminates the specimen and can be adjusted using a dimmer or on/off switch.
-
Base: Acts as the foundation of the microscope and contains the light source.
-
Microscope Slide: Thin glass surface, approximately 1mm thick, used for securing specimens under observation.
-
Coverslip: A thin glass sheet placed over specimens on the slide, helping to keep them in place.
