Study Notes
Microscope Overview
- An optical instrument designed to view structures not visible to the naked eye.
- Composed of multiple lenses providing varying levels of magnification.
- Features two sets of lenses: one in the eyepiece (ocular lens) and another in the objectives.
Parts of a Compound Microscope
- Eyepiece (Panipat): The lens through which the user looks; typically has a magnification of 10x.
- Draw Tube (Hil ahing tubo): A tube that connects the eyepiece to the body tube.
- Coarse Adjustment Knob (Dagling pahusay): Quickly changes the elevation of the tube for initial focusing.
- Fine Adjustment Knob (Dahang pahusay): Allows for precise adjustments in the tube’s elevation for accurate focusing.
- Body Tube (Katawang tubo): Houses the eyepiece at the top and objectives at the bottom, maintaining alignment.
- Revolving Nosepiece (Ikuting panaklaw): Holds multiple objectives and allows easy switching between them.
- Objectives (Panaklaw): The lenses attached to the nosepiece for different magnification levels.
- Stage (Tang halan): The flat platform where slides are placed for examination.
- Clip (Pang-ipit): Secures the slide on the stage to prevent movement.
- Mirror (Salamin): Reflects light to illuminate the specimen; one side is plain for natural light, the other concave for artificial light.
- Base (Takad): The sturdy bottom part that supports the entire microscope structure.
- Pillar (Patindig): Vertical support extending from the base, supporting the stage and body tube.
- Inclination Joint (Sugpong-panghilig): Allows the microscope to tilt at various angles for better viewing.
- Diaphragm (Alikmata): Regulates light passing through to enhance clarity while viewing specimens.
Functions of Key Parts
- Stage and Clip: Securely holds the slide in place for examination.
- Mirror: Essential for proper lighting of the specimen.
- Revolving Nosepiece & Objectives: Facilitate switching between different magnification levels to observe details.
