Study Notes
Compound Light Microscope Components and Functions
- The eyepiece is responsible for magnifying the image formed by the objective lens, allowing the observer to view the specimen.
Stage and Slide Handling
- The stage holds the slide and has a window that allows light to pass through the specimen, enabling observation.
Revolving Nosepiece
- The revolving nosepiece allows for easy rotation and interchange of objective lenses, making it convenient to switch between different magnifications.
Microscope Operation
- The coarse adjustment knob should NOT be used with high power objective lenses to avoid damaging the lens or the specimen.
Objective Lenses
- The objective lens is responsible for collecting and focusing light from the specimen, forming an image that is then magnified by the eyepiece.
- The shortest objective lens (scanning lens) is closest to the specimen, while the longest objective lens (oil immersion lens) is farthest from the specimen.
Diaphragm Function
- The diaphragm regulates the amount of light that reaches the specimen, controlling the contrast and resolution of the image.
Lens Order and Focal Length
- The correct order of lenses from shortest to longest focal length is: scanning lens, low power lens, high power lens, and oil immersion lens.
