Study Notes
Compound Microscope Parts and Functions
-
Arm: Connects the body tube to the base; essential for transporting the microscope.
-
Base: The foundational part of the microscope; supports the entire structure.
-
Eyepiece: Viewing point for the user; includes two or more lenses. Common magnifications are 10x, 2x, and 5x; interchangeable with other eyepieces.
-
Objective Lenses: Typically two primary lenses with various magnifications (4x, 5x, 10x, 20x, 40x, 50x, 100x). Attached to an objective turret that allows for rotation to change magnification and focus.
-
Stage: The platform where specimens are placed; features a hole to allow light to illuminate the specimen from below.
-
Stage Clips: Two clips positioned on either side of the stage; used to secure slides containing specimens in place.
-
Diaphragm: Located on the lower stage; regulates light intensity reaching the specimen through the stage hole.
-
Illuminator: Provides light for viewing the specimen; can be a movable mirror in basic models or have an integrated light source in advanced microscopes.
-
Adjustments: Comprises the coarse adjustment knob (for focusing at low power) and the fine adjustment knob (for precise focusing at higher magnifications).
