Study Notes
Microscope Components
- The mirror is planar on one side and spherical on the other.
- The flat side of the mirror is used for reflected light.
Illumination System
- The condenser concentrates light from the light source or mirror onto the object or specimen being studied and is located below the stage.
- The iris diaphragm regulates the amount of light that reaches the specimen.
Image Formation
- The eyepiece or ocular is the part through which an observer looks to view a specimen and usually has a magnification of 10x.
- The objectives are the main lenses that magnify the specimen being observed and typically have magnifying powers of 4x, 10x, 40x, and even 100x.
Microscope Structure
- The body tube is a hollow tube through which light passes from the objective to the eyepiece.
- The revolving nosepiece holds the objectives and can be rotated to select the appropriate objective.
