Study Notes
Microscope Parts
- The ocular lens is what you look through to view a specimen.
- Objective lenses are attached to the revolving nosepiece, which allows you to switch between different magnifications (low, medium, high power).
- The coarse adjustment knob is used for initial focusing, especially on low power.
- The fine adjustment knob is used for precise focusing, especially on medium and high power.
- The diaphragm controls the amount of light passing through the specimen.
- The stage is the flat platform where you place the slide.
- The light source provides illumination for viewing the specimen.
- The base provides stability and is used for carrying the microscope.
- The field of view refers to the circular area visible through the microscope.
- Objective lens power indicates the magnification of each objective lens (e.g., 40x).
- Ocular lens power is the magnification of the eyepiece (e.g., 10x).
- The magnification of a microscope is calculated by multiplying the ocular lens power by the objective lens power.
- A wet mount is a slide with a drop of water on it, often used to improve viewing of specimens.
- A slide is a thin, flat piece of glass used to hold and view specimens, including bacteria.
