Study Notes
Light Microscope Parts and Functions
-
Eyepiece: Contains the ocular lens for viewing; typically has a built-in magnification feature.
-
Nosepiece: Holds the objective lenses and allows for rotation to change magnification levels.
-
Objective Lens: Provides magnification options ranging from 4x to 40x, allowing for various levels of detail.
-
Stage Clips: Secure the slide in place during observation to ensure stability.
-
Stage: The flat surface that supports the slide being examined.
-
Light Source: Illuminates the specimen by projecting light upward through the diaphragm and lenses.
-
Arm: The structure used for supporting and carrying the microscope safely.
-
Course Adjustment Knob: Adjusts the stage height significantly to find general focus when viewing samples.
-
Fine Adjustment Knob: Makes minor adjustments to the stage for fine-tuning the focus and sharpening images.
-
Diaphragm: Controls the light intensity reaching the specimen, enhancing visibility and contrast.
-
Base: The bottom part that provides overall stability and support to the microscope.
-
Magnification Levels (4x, 10x, 40x): Images may not be centered directly; sliding adjustments are required when changing magnification settings.
